A sample of gas at temperature $T$ is adiabatically expanded to double its volume. The work done by the gas in the process is $\left(\right.$ given, $\left.\gamma=\frac{3}{2}\right)$ :
$W=T R[\sqrt{2}-2]$
$W=\frac{T}{R}[\sqrt{2}-2]$
$W=\frac{R}{T}[2-\sqrt{2}]$
$W=R T[2-\sqrt{2}]$
If $\gamma $ denotes the ratio of two specific heats of a gas, the ratio of slopes of adiabatic and isothermal $PV$ curves at their point of intersection is
A gas at initial temperature $T$ undergoes sudden expansion from volume $V$ to $2 \,V$. Then,
$Assertion :$ Air quickly leaking out of a balloon becomes cooler.
$Reason :$ The leaking air undergoes adiabatic expansion.
A sample of gas with $\gamma=1.5$ is taken through an adiabatic process in which the volume is compressed from $1200\, {cm}^{3}$ to $300\, {cm}^{3}$. If the initial pressure is $200\, {kPa}$. The absolute value of the workdone by the gas in the process $= \,..... J.$
The adiabatic Bulk modulus of a diatomic gas at atmospheric pressure is
