Thermodynamic Processes

A fixed mass of gas at constant pressure occupies a volume ' V '. The gas undergoes a rise in temperature so that the r.m.s. velocity of the molecules is doubled. The new volume will be

Show answer and solution

Answer: (d)

$v_{rms} \propto \sqrt{T}$ : doubling $v_{rms}$ makes $T' = 4T$ .
At constant pressure $V \propto T$ , so $V' = 4V$ .
So the answer is (d) $4V$ .
