Solutions Class 12 NCERT Solutions – Questions and Answers for All Subjects

Sample Questions and Answers:

Physics

  1. What is the principle behind the working of a transformer?

    • A transformer works on the principle of electromagnetic induction, where alternating current in a primary coil induces a varying magnetic flux that induces voltage in the secondary coil.
  2. Define Ohm’s law and explain its significance.

    • Ohm’s law states that the current through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance, i.e., V = IR.
  3. What is the difference between conduction and convection?

    • Conduction is the transfer of heat through direct contact of molecules, while convection involves the movement of fluid (liquid or gas) transferring heat.
  4. Explain the law of conservation of momentum.

    • The law states that the total momentum of a closed system remains constant if no external force acts on it.
  5. What is meant by the term "electric field"?

    • An electric field is a region around a charged object where other charges experience a force.

Chemistry

  1. Define molarity and explain how it differs from molality.

    • Molarity is the number of moles of solute per liter of solution, while molality is the number of moles of solute per kilogram of solvent.
  2. What are colligative properties?

    • Colligative properties depend on the number of solute particles in a solvent, not their identity, such as boiling point elevation and freezing point depression.
  3. What is an acid-base titration?

    • It is a technique to determine the concentration of an acid or base by reacting it with a base or acid of known concentration.
  4. Explain the term "activation energy" in a chemical reaction.

    • Activation energy is the minimum energy required to initiate a chemical reaction.
  5. What is the significance of Le Chatelier’s principle?

    • Le Chatelier’s principle states that if a system at equilibrium is disturbed, the system will shift in a direction to counteract the disturbance.

Mathematics

  1. What is the formula for the area of a circle?

    • The area of a circle is given by A = πr², where r is the radius of the circle.
  2. How do you calculate the roots of a quadratic equation?

    • The roots of a quadratic equation ax² + bx + c = 0 can be found using the quadratic formula, x = [-b ± √(b² - 4ac)] / 2a.
  3. Define a vector in mathematics.

    • A vector is a quantity that has both magnitude and direction, represented in coordinates like (x, y) in two-dimensional space.
  4. What is the difference between permutation and combination?

    • Permutation refers to the arrangement of objects in a specific order, while combination is the selection of objects without considering the order.
  5. What is the area of a triangle?

    • The area of a triangle is given by A = 1/2 * base * height.

Biology

  1. What is photosynthesis?

    • Photosynthesis is the process by which green plants use sunlight, carbon dioxide, and water to produce glucose and oxygen.
  2. Explain Mendel’s law of inheritance.

    • Mendel’s laws of inheritance describe how traits are passed from parents to offspring through genes, explaining dominant and recessive traits.
  3. What is the function of the human circulatory system?

    • The circulatory system is responsible for transporting blood, nutrients, oxygen, and waste products throughout the body.
  4. Describe the process of digestion.

    • Digestion involves breaking down food into simpler molecules in the gastrointestinal tract, starting from the mouth and ending at the small intestine.
  5. What is the role of enzymes in biological processes?

    • Enzymes act as catalysts that speed up chemical reactions in the body without being consumed in the process.
