Draw $P-V$ curves for isothermal and adiabatic processes of an ideal gas.
(N/A) The $P-V$ diagram represents a Carnot cycle,which consists of two isothermal processes and two adiabatic processes.
$1$. Isothermal expansion: The gas expands at a constant temperature.
$2$. Adiabatic expansion: The gas expands without any heat exchange with the surroundings.
$3$. Isothermal compression: The gas is compressed at a constant temperature.
$4$. Adiabatic compression: The gas is compressed without any heat exchange with the surroundings.
The adiabatic curves are steeper than the isothermal curves because the adiabatic bulk modulus is $\gamma$ times the isothermal bulk modulus,where $\gamma > 1$.

One mole of an ideal diatomic gas expands from volume $V$ to $2V$ isothermally at a temperature $27^{\circ} C$ and does $W$ joule of work. If the gas undergoes the same magnitude of expansion adiabatically from $27^{\circ} C$ doing the same amount of work $W$, then its final temperature will be (close to) . . . . . . ${ }^{\circ} C$.
$A$ gas undergoes a change of state during which $100 \ J$ of heat is supplied to it and it does $20 \ J$ of work. The system is brought back to its original state through a process during which $20 \ J$ of heat is released by the gas. The work done by the gas in the second process is ....... $J$
