Properties of bulk matter refer to the physical characteristics and behavior of matter in its macroscopic form. Here are some important properties of bulk matter in chemistry:

1. Density: Density is defined as the mass per unit volume of a substance. The density of a substance is an important property that can help to identify the substance and also to determine the amount of a substance present in a given volume.
2. Elasticity: Elasticity is the ability of a substance to recover its original shape and size after being deformed by an external force. The extent of elasticity depends on the nature of the material and the amount of deformation.
3. Surface Tension: Surface tension is the tendency of liquids to minimize their surface area. It is the force per unit length acting on the surface of a liquid. Surface tension is responsible for the shape of droplets and the ability of insects to walk on water.
4. Viscosity: Viscosity is a measure of a substance’s resistance to flow. It is a result of intermolecular forces that exist between the particles of the substance. The higher the viscosity of a substance, the slower it will flow.
5. Cohesion and Adhesion: Cohesion is the force of attraction between particles of the same substance, whereas adhesion is the force of attraction between particles of different substances. Cohesion is responsible for the formation of drops, whereas adhesion is responsible for the ability of water to wet glass.
6. Thermal Expansion: Thermal expansion is the increase in the volume of a substance due to an increase in temperature. The extent of thermal expansion depends on the nature of the material.
7. Heat Capacity: Heat capacity is the amount of heat required to raise the temperature of a substance by one degree Celsius. It is a measure of the amount of energy required to change the temperature of a substance.

These properties of bulk matter have important practical applications in fields such as engineering, materials science, and medicine.

Matter

In traditional physical science and general science, matter is any substance that has mass and occupies room by having volume. All regular articles that can be contacted are eventually made out of molecules, which are comprised of communicating subatomic particles, and in ordinarily as well as logical use, “matter” by and large incorporates iotas and anything comprised of them, and any particles (or blend of particles) that go about as though they have both rest mass and volume. Anyway it does exclude massless particles like photons, or other energy peculiarities or waves like light or heat. 21 Matter exists in different states (otherwise called stages). These incorporate traditional regular stages like strong, fluid, and gas – for instance water exists as ice, fluid water, and vaporous steam – yet different states are conceivable, including plasma, Bose-Einstein condensates, fermionic condensates, and quark-gluon plasma.

Typically molecules can be envisioned as a core of protons and neutrons, and an encompassing “cloud” of circling electrons which “take up space”. Anyway this is just fairly right, in light of the fact that subatomic particles and their properties are represented by their quantum nature, and that implies they don’t go about as regular items seem to act – they can carry on like waves as well as particles and they don’t have clear cut sizes or positions. In the Standard Model of molecule material science, matter is definitely not a crucial idea on the grounds that the rudimentary constituents of particles are quantum elements which don’t have an intrinsic “size” or “volume” in any regular feeling of the word. Because of the prohibition rule and other essential collaborations, some “point particles” known as fermions (quarks, leptons), and numerous composites and iotas, are successfully compelled to stay away from different particles under ordinary circumstances; this makes the property of issue which appears to us as issue occupying room.

For a large part of the historical backdrop of the innate sciences individuals have mulled over the specific idea of issue. The possibility that matter was worked of discrete structure obstructs, the purported particulate hypothesis of issue, showed up in both antiquated Greece and old India. Early scholars who proposed the particulate hypothesis of issue incorporate the old Indian savant Kaneda (c. sixth century BCE or after), pre-Socratic Greek rationalist Leucippus (~490 BCE), and pre-Socratic Greek thinker Democritus (~470-380 BCE).

History of NEET-CHEMISTRY Properties of bulk Matter

The study of properties of bulk matter has a long history in chemistry and physics. Here are some significant historical events related to the development of our understanding of these properties:

1. Archimedes’ Principle (3rd century BC): The Greek mathematician Archimedes discovered the principle of buoyancy, which states that a body immersed in a fluid experiences an upward force equal to the weight of the displaced fluid. This principle is important in understanding the behavior of fluids and objects floating in them.
2. Boyle’s Law (1662): Robert Boyle, an Irish physicist, discovered the relationship between the pressure and volume of a gas. Boyle’s Law states that at a constant temperature, the pressure of a gas is inversely proportional to its volume. This law has important applications in the study of gases.
3. Gay-Lussac’s Law (1802): Joseph Louis Gay-Lussac, a French chemist, discovered the relationship between the pressure and temperature of a gas. Gay-Lussac’s Law states that at a constant volume, the pressure of a gas is directly proportional to its temperature. This law also has important applications in the study of gases.
4. Surface Tension (19th century): Surface tension was first studied in the 19th century by physicists such as Lord Rayleigh and J.J. Thomson. They discovered that the force responsible for surface tension is due to the attractive forces between the molecules at the surface of a liquid.
5. Heat Capacity (19th century): The concept of heat capacity was first introduced in the 19th century by the French physicist Nicolas Léonard Sadi Carnot. Heat capacity is an important property of materials, as it determines the amount of energy required to change their temperature.
6. Modern Developments (20th century): In the 20th century, new techniques such as X-ray diffraction and electron microscopy were developed, which allowed scientists to study the properties of materials at the atomic and molecular level. This led to a better understanding of the relationship between the microscopic properties of materials and their macroscopic behavior.

Overall, the history of the study of properties of bulk matter is a long and rich one, with contributions from many scientists over several centuries.

Nature of NEET-CHEMISTRY Properties of bulk Matter

Properties of bulk matter in chemistry are physical characteristics and behaviors that can be observed and measured in macroscopic or bulk form. These properties are a result of the arrangement and interaction of the constituent particles that make up the material.

The behavior of a material can be described in terms of its physical properties, such as its density, elasticity, surface tension, viscosity, cohesion, adhesion, thermal expansion, and heat capacity. These properties are determined by the types of intermolecular and interatomic forces that exist within the material, such as van der Waals forces, hydrogen bonding, covalent bonding, and metallic bonding.

For example, the density of a material is determined by the packing efficiency of its constituent particles, with a higher density indicating that the particles are packed more tightly. The surface tension of a liquid is determined by the attractive forces between the molecules at its surface. The thermal expansion of a material is determined by the changes in the distances between its constituent particles due to changes in temperature.

Properties of bulk matter can also be influenced by external factors, such as temperature, pressure, and electromagnetic fields. For example, the viscosity of a material can change with temperature, with higher temperatures causing a decrease in viscosity. The elasticity of a material can be affected by pressure, with increased pressure causing an increase in elasticity.

Understanding the nature of properties of bulk matter is important in many fields, such as materials science, engineering, and medicine, as it allows us to develop new materials with desired properties and to predict and control the behavior of existing materials.

System of NEET-CHEMISTRY Properties of bulk Matter

In the context of chemistry, a system refers to a specific portion of matter or substance under study, while the surroundings include everything outside the system. The system and its surroundings can exchange energy and matter, and these exchanges can affect the properties of the system.

The properties of bulk matter can be studied by considering a system of matter and observing how its properties change when subjected to various external factors, such as temperature, pressure, or electromagnetic fields. The system can be classified based on its nature and the type of matter it contains. Some common systems used to study properties of bulk matter are:

1. Homogeneous system: A homogeneous system is one in which the composition and properties of the material are uniform throughout. For example, a solution of salt in water is a homogeneous system, as the properties of the solution are the same regardless of the location within the solution.
2. Heterogeneous system: A heterogeneous system is one in which the composition and properties of the material are not uniform throughout. For example, a mixture of oil and water is a heterogeneous system, as the oil and water do not mix and the properties of the mixture vary depending on the location within the mixture.
3. Open system: An open system is one in which matter and energy can be exchanged with the surroundings. For example, a beaker of water open to the atmosphere is an open system, as water can evaporate and energy can be exchanged with the surroundings.
4. Closed system: A closed system is one in which energy can be exchanged with the surroundings, but matter cannot. For example, a sealed container of gas is a closed system, as energy can be exchanged with the surroundings through heating or cooling, but the gas cannot escape.
5. Isolated system: An isolated system is one in which neither matter nor energy can be exchanged with the surroundings. For example, a thermos flask containing hot coffee is an isolated system, as the coffee cannot exchange heat with the surroundings and cool down.

The study of properties of bulk matter in chemistry involves considering these different types of systems and observing how the properties of the system change under different conditions. By understanding the behavior of a system, we can predict and control the properties of bulk matter, which has important practical applications in many fields, including materials science, engineering, and medicine.
