Physics
Question: What is Newton’s First Law of Motion?
Answer: Newton’s First Law of Motion states that a body at rest will remain at rest, and a body in motion will remain in uniform motion unless acted upon by an external force.
Question: Define the term ‘moment of inertia.’
Answer: Moment of inertia is the measure of an object’s resistance to changes in its rotational motion about an axis.
Question: What is the law of conservation of energy?
Answer: The law of conservation of energy states that energy can neither be created nor destroyed; it can only be transformed from one form to another.
Question: What is the difference between scalar and vector quantities?
Answer: Scalar quantities have only magnitude, while vector quantities have both magnitude and direction.
Question: Explain Hooke’s Law in elasticity.
Answer: Hooke’s Law states that the deformation of an elastic material is proportional to the applied force, provided the limit of elasticity is not exceeded.
Question: What is the Doppler Effect?
Answer: The Doppler Effect refers to the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.
Question: Define work-energy theorem.
Answer: The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy.
Question: What is Snell’s Law in optics?
Answer: Snell’s Law states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant for two given media.
Question: Explain the concept of simple harmonic motion (SHM).
Answer: SHM is a type of oscillatory motion where the restoring force is directly proportional to displacement and acts in the opposite direction.
Question: What is the principle of superposition in waves?
Answer: The principle of superposition states that when two or more waves overlap, the resultant displacement is the algebraic sum of the displacements of the individual waves.
Question: Define thermal conductivity.
Answer: Thermal conductivity is the property of a material that indicates its ability to conduct heat.
Question: What is the difference between reflection and refraction?
Answer: Reflection is the bouncing back of light from a surface, while refraction is the bending of light as it passes from one medium to another.
Question: What is the critical angle in optics?
Answer: The critical angle is the angle of incidence at which light is refracted along the boundary of two media, resulting in total internal reflection.
Question: Explain the concept of entropy in thermodynamics.
Answer: Entropy is a measure of the disorder or randomness of a system. It quantifies the amount of energy unavailable for doing work.
Question: Define electric flux.
Answer: Electric flux is the measure of the number of electric field lines passing through a given surface area.
Question: What is a capacitor, and how does it work?
Answer: A capacitor is an electrical component that stores energy in the form of an electric field, working by accumulating opposite charges on its plates.
Question: What is Faraday’s Law of Electromagnetic Induction?
Answer: Faraday’s Law states that a change in magnetic flux through a circuit induces an electromotive force in the circuit.
Question: What is the concept of wave-particle duality?
Answer: Wave-particle duality is the principle that particles like electrons exhibit both wave-like and particle-like properties.
Question: What is a black body in physics?
Answer: A black body is an idealized object that absorbs all incident electromagnetic radiation and emits radiation characteristic of its temperature.
Chemistry
Question: What is the atomic number of an element?
Answer: The atomic number is the number of protons in the nucleus of an atom of an element.
Question: Define isotopes.
Answer: Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons.
…
Question: What is the law of conservation of mass in chemistry?
Answer: The law of conservation of mass states that mass is neither created nor destroyed during a chemical reaction; it remains constant.
Question: Explain the term ‘mole’ in chemistry.
Answer: A mole is a unit representing 6.022 × 10²³ particles (atoms, molecules, or ions) of a substance.
Question: What is the pH scale?
Answer: The pH scale measures the acidity or alkalinity of a solution, ranging from 0 (acidic) to 14 (alkaline), with 7 being neutral.
Question: What is Avogadro’s Law?
Answer: Avogadro’s Law states that equal volumes of gases at the same temperature and pressure contain an equal number of molecules.
Question: What is a covalent bond?
Answer: A covalent bond is a chemical bond formed by the sharing of electron pairs between atoms.
Question: Define oxidation and reduction.
Answer: Oxidation is the loss of electrons, while reduction is the gain of electrons during a chemical reaction.
Question: What are hydrocarbons?
Answer: Hydrocarbons are organic compounds composed entirely of carbon and hydrogen atoms.
Question: Explain Le Chatelier’s Principle.
Answer: Le Chatelier’s Principle states that if a dynamic equilibrium is disturbed, the system will adjust to minimize the disturbance and restore equilibrium.
Question: What is the difference between exothermic and endothermic reactions?
Answer: Exothermic reactions release energy in the form of heat, while endothermic reactions absorb energy from the surroundings.
Question: What is a catalyst?
Answer: A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.
Question: Define isomerism.
Answer: Isomerism is the phenomenon where compounds have the same molecular formula but different structural arrangements.
Question: What are acids and bases?
Answer: Acids are substances that release hydrogen ions (H⁺) in solution, while bases release hydroxide ions (OH⁻).
Question: What is the Periodic Table?
Answer: The Periodic Table is a tabular arrangement of chemical elements, organized by increasing atomic number and similar properties.
Question: What is electrolysis?
Answer: Electrolysis is a chemical process where electrical energy is used to drive a non-spontaneous chemical reaction.
Question: What are alloys?
Answer: Alloys are mixtures of two or more elements, where at least one is a metal, designed to enhance specific properties.
Question: What is the principle of chromatography?
Answer: Chromatography separates components of a mixture based on their different affinities to a stationary and a mobile phase.
Question: What is the difference between ionic and covalent bonds?
Answer: Ionic bonds involve the transfer of electrons between atoms, while covalent bonds involve the sharing of electrons.
Question: Define the term ‘molarity.’
Answer: Molarity is the concentration of a solution expressed as moles of solute per liter of solution.
Question: What is a chemical equilibrium?
Answer: Chemical equilibrium occurs when the rates of the forward and reverse reactions in a chemical system are equal, resulting in no net change in concentrations.
Mathematics
Question: What is the Pythagorean Theorem?
Answer: The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
