The temperature of an ideal gas is kept constant as it expands. The gas does external work. During this process,the internal energy of the gas

An ideal gas at pressure $P$ is enclosed in a container that is placed in a reservoir at temperature $T$. If the volume of the gas is increased to two times its original value,then the new pressure $P^{\prime}$ is equal to:

$A$ thermodynamic process in which the temperature $T$ of the system remains constant,although other variables $P$ and $V$ may change,is called:

$A$ gas undergoes a change at constant temperature. Which of the following quantities remain fixed?

The specific heat of an isothermal process is:

$A$ gas is compressed at constant temperature. Its molecules gain:
