In a given reversible process,the temperature of an ideal gas is kept constant as the gas is compressed to a smaller volume.Which one of the following statements about the gas is correct?

Question

Quizplus · Accepted Answer

In a reversible isothermal compression of an ideal gas, the gas must release thermal energy to its surroundings to maintain a constant temperature, as work is done on the gas to compress it. This is in accordance with the first law of thermodynamics, which states that the internal energy change in a system is equal to the heat added to the system minus the work done by the system. Since the internal energy of an ideal gas in an isothermal process does not change (because internal energy is a function of temperature only and the temperature is constant), the work done on the gas must be released as heat to the surroundings.
