Young’s modulus of a metallic wire is determined by measuring its original length and cross-sectional area, applying known loads, measuring the small extension…
ATP (Adenosine Triphosphate): ATP is a mononucleotide consisting of adenine (a nitrogen base), ribose (a five-carbon sugar), and three phosphates. It is…
A gas transfers energy by doing pressure-volume work. At constant external pressure, work done by the gas is W = PΔV, and the area under a pressure-volume…
Normal Flora: Normal flora is the term used to describe the various bacteria (and fungi) that are permanent residents of certain body parts, especially the…
Ultrastructure is the fine structure of the cell as seen with the electron microscope. In simple words: Ultrastructure means the very detailed internal…
Respiratory Surface: The area where gaseous exchange with the environment actually takes place is called the respiratory surface.
The main idea is that the ease of hydrolysis of these compounds follows the order: Acyl chlorides > Alkyl chlorides > Aryl chlorides…
Law of Mass Action: The rate at which a substance reacts is proportional to its active mass and the rate of a chemical reaction is proportional to the…
Moment of inertia describes how strongly an object resists a change in its rotational motion. It is also called rotational inertia. An object is harder to…
Role of Chemical Kinetics in the Food Industry: The application of the principles of reaction rates and collision theory to understand, control, and…
Allied angles are built from A by adding or subtracting 90, 180, 270, 360 (and negatives). Examples: sin(180-A)=sin A, cos(180-A)=-cos A, tan(180-A)=-tan A.…
For algebraic expressions, factorise first. HCF is the product of common factors with the lowest powers. LCM is the product of all factors with the highest…
Combustion is the rapid reaction of a substance with oxygen, producing heat and light. For alkanes, combustion produces: · Carbon dioxide (CO₂)…
Sustainability meets present needs while preserving future ecological capacity. Population, consumption, efficiency, equity and technology jointly determine…
The Contact Process is the industrial process used for manufacturing sulfuric acid.
A measuring cylinder is a tool used in laboratories to measure the volume of liquids, chemicals, or solutions. It is a transparent glass or plastic tube…
Compare totals and samples with source queries, test empty and large datasets, and confirm filters before distribution.
Radius, half-chord, and distance from centre make a right triangle. Almost every numerical chord question is this one triangle. Diameter as hypotenuse: angle…
Refinery gas, petrol, naphtha, kerosene, diesel, residue. Higher up the tower: lower b.p., smaller molecules, more volatile, lower viscosity (school table).…
Atom: The smallest indivisible particle of matter that cannot be cut or divided further. The word atom comes from the Greek word "atomos"
Acceleration is the measure of change in velocity (Δ v) with the passage of time (Δ t). It is the rate of change of velocity. It is…
Central Nervous System (CNS): The central nervous system consists of the brain and spinal cord. Both are hollow. They are covered with three protective…
