FAQs on Heat obtained due to expansion of 1 mol of H2 gas at 1000 K from 10 L to 100 L Video Lecture - JEE

1. How do I calculate the heat obtained due to the expansion of a gas?
Ans. The heat obtained due to the expansion of a gas can be calculated using the formula Q = nCpΔT, where Q is the heat obtained, n is the number of moles of the gas, Cp is the molar heat capacity at constant pressure, and ΔT is the change in temperature.
2. What is the molar heat capacity at constant pressure?
Ans. The molar heat capacity at constant pressure (Cp) is the amount of heat required to raise the temperature of one mole of a substance by one degree Celsius at constant pressure. It is a property that depends on the nature of the substance.
3. How do I calculate the change in temperature during the expansion of a gas?
Ans. The change in temperature (ΔT) during the expansion of a gas can be calculated using the formula ΔT = Tf - Ti, where Tf is the final temperature and Ti is the initial temperature.
4. Can the heat obtained during the expansion of a gas be negative?
Ans. Yes, the heat obtained during the expansion of a gas can be negative. A negative value indicates that heat is lost by the system during the expansion process.
5. Is the heat obtained during the expansion of a gas the same as the work done by the gas?
Ans. No, the heat obtained during the expansion of a gas is not the same as the work done by the gas. Heat is a form of energy transfer, while work is the energy transferred by a force acting through a distance. The heat obtained is related to the change in temperature, while the work done is related to the change in volume.
