³₂He and ³₁H nuclei have the same mass number. Do they have the same binding energy?
No, ³₂He and ³₁H nuclei do not have the same binding energy. Although they have the same mass number, their nuclear structures and binding energies differ, as binding energy depends on proton-neutron interactions and nuclear stability.

Name the reaction responsible for energy production in the Sun.
The energy production in the Sun is primarily due to the proton-proton chain reaction. In this process, hydrogen nuclei fuse to form helium, releasing vast amounts of energy in the form of light and heat.

Four nuclei of an element undergo fusion to form a heavier nucleus, with release of energy. Which of the two – the parent or the daughter nucleus – would have higher binding energy per nucleon?
The daughter nucleus would have a higher binding energy per nucleon. Fusion typically results in a more stable, heavier nucleus, where nucleons are more tightly bound, releasing energy. This is because the binding energy increases with atomic mass. For more visit here: https://www.tiwariacademy.com/Read more

Define the terms specific heat and molar specific heat. Give their CGS and SI units.
Specific heat is the quantity of heat necessary to raise the temperature of 1 unit mass of a substance by 1°C or 1 K. Molar specific heat is the quantity of heat necessary to raise the temperature of 1 mole of a substance by 1°C or 1 K. CGS units: - Specific heat: cal/g°C - Molar specific heat: cal/Read more

What do you mean by coefficients of apparent and real expansion of a liquid ? How are they related?
The coefficient of apparent expansion of a liquid is the increase in volume per unit volume of the liquid when heated, as measured by a container. It takes into account both the expansion of the liquid and the container. The coefficient of real expansion of a liquid is the actual increase in volumeRead more
The coefficient of apparent expansion of a liquid is the increase in volume per unit volume of the liquid when heated, as measured by a container. It takes into account both the expansion of the liquid and the container.
The coefficient of real expansion of a liquid is the actual increase in volume per unit volume of the liquid, ignoring the effects of the container.
The relation between the two is given as:
Real expansion = Apparent expansion + Coefficient of linear expansion of the container × Coefficient of volume expansion of the container
