Q. $3$ moles of an ideal gas are contained within a cylinder by a frictionless piston and are initially at temperature $T$. The pressure of the gas remains constant while it is heated and its volume doubles. If $R$ is molar gas constant, the work done by the gas in increasing its volume is

Thermodynamics

Solution:

$W=P \Delta V$
$=P V$
$=n R T$
$=3 R T$
