Question

$3$ 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:

• A. $\frac{3}{2}RT$ $In$ $2$
• B. $3RT$ In $2$
• C. $\frac{3}{2}RT$
• D. $3RT$

Answer 1

The correct option is D $3RT$

D is the correct option.
