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
(1) 3/2RTIn2
(2) 3 RT In 2
(3) 3/2RT
(4) 3 RT

Answer:
3RT (Option-4)
Explanation:
We know that,
work done at constant pressure , W=(P)x(V2-V1)
We know, PV=NRT
P=NRT/V
W=(NRT)(2V-V)/V
W=(NRT)(1)
Here,N=3
Therefore, W=3RT.

The work done by the gas in increasing its volume is 3RT
Explanation:
Number of moles of an ideal gas=n=3
Let P be the constant pressure of the gas
Let Initial volume of gas=
Final volume of gas=2V
Change in volume=2V-V=V
Molar gas constant=R
Work done=
Where P=Constant pressure
=Change in volume
We know that
Work done=
Substitute the values then we get
Work done=
Option (4) is true.
