Question

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

A. The gas must absorb heat from its surroundings.
B. The gas must release heat to its surroundings.
C. The pressure of the gas also stays constant.
D. The process is adiabatic.

Answer 1

B. The gas must release heat to its surroundings.

Step-by-step explanation:

Since the process is reversible , it must be slow . Since temperature is kept constant so the internal energy is constant , Since volume is decreased , pressure must be increased. Since work is done on the gas ( gas is compressed ) , so heat must be released by the gas so that its internal energy remains constant.
