An ideal gas expands isothermally along $ab$ and does $600\,J$ of work. During the process,

The work done in doubling the volume of $5$ moles of an ideal gas at a constant temperature of $500 \, K$ is ....... $J$.

If an ideal gas is compressed isothermally,then:

If an ideal gas is compressed isothermally, which of the following statements is true?

When heat is given to a gas in an isothermal change,the result will be

$A$ vertical cylinder with heat-conducting walls is closed at the bottom and is fitted with a smooth light piston. It contains one mole of an ideal gas. The temperature of the gas is always equal to the surrounding's temperature,$T_0$. The piston is moved up slowly to increase the volume of the gas to $\eta$ times. Which of the following is incorrect?
