A mass of gas is first expanded isothermally and then compressed adiabatically to its original volume. What further simplest operation must be performed on the gas to restore it to its original state?
Options:
Answer:
B
Solution:
After isothermal expansion then adiabatic compression back to the original volume, the temperature is above the initial value. At the original volume, cooling at constant volume brings the pressure (and temperature) back to the initial state.
