Enzyme catalysis Enzyme catalysis refers to the process by which enzymes facilitate and accelerate biochemical reactions in living organisms. Enzymes are specialized proteins that act as biological catalysts, lowering the activation energy required for a reaction to occur. This allows the reaction to proceed at a faster rate, enabling vital cellular processes to take place.…
Temperature Temperature is a fundamental physical quantity that measures the hotness or coldness of an object or a system. It is a scalar quantity and is typically measured in units such as Celsius (°C), Fahrenheit (°F), or Kelvin (K). Temperature is a macroscopic property that is related to the average kinetic energy of the particles…
The solubility of the gas in liquids The solubility of a gas in a liquid refers to the ability of the gas to dissolve in the liquid. It is a measure of the maximum amount of gas that can be dissolved in a given quantity of the liquid at a specific temperature and pressure. The…
Solutions Here are some common topics covered in the chemistry syllabus for medical entrance exams: This is just a general outline, and the actual syllabus may include additional topics or subtopics. I recommend referring to the official AIIMS syllabus or any course materials provided by the institute for more accurate and detailed information. What is…
Crystalline Solids Crystalline solids are a type of solid material characterized by their highly ordered and repeating three-dimensional arrangement of atoms, ions, or molecules. This regular arrangement gives crystalline solids their distinct crystalline structure and various properties. Here are some key features and properties of crystalline solids: The study of crystalline solids is essential in…
Amorphous Amorphous is a term used in materials science to describe a solid substance that lacks a definite long-range order in its atomic or molecular structure. Unlike crystalline materials, which have a regular and repeating arrangement of atoms or molecules, amorphous materials have a disordered arrangement. In amorphous substances, the atoms or molecules are randomly…
Metallic Solids Metallic solids are a type of solid material characterized by a lattice structure composed of metal atoms or ions. They exhibit metallic bonding, which is responsible for their unique properties such as high electrical conductivity, thermal conductivity, and malleability. Here are some key features and characteristics of metallic solids: These are some of…
Ionic covalent “Ionic” and “covalent” are terms used to describe the types of chemical bonds that can form between atoms. Ionic Bond: An ionic bond is formed when one or more electrons are transferred from one atom to another. This results in the formation of positively charged ions (cations) and negatively charged ions (anions). The…
Solid state The solid state is a state of matter characterized by a definite shape and volume. In the solid state, particles (atoms, ions, or molecules) are closely packed and held together by strong intermolecular forces. This results in a rigid structure with a fixed arrangement of particles. Here are some key aspects and properties…
Matter waves Matter waves, also known as de Broglie waves, are a fundamental concept in quantum mechanics that describes the wave-like behavior of particles. According to the wave-particle duality principle, particles, such as electrons, protons, and even larger objects like atoms and molecules, can exhibit wave-like properties. The concept of matter waves originated from Louis…
