A cylinder with fixed capacity 67.2 lit contains helium gas at STP.
The amount of heat needed to raise the temperature of the gas by
is : [ Given that ]
350 J
374 J
748 J
700 J
Specific heat for isochoric process -
- wherein
is degree of freedom
1 mole at STP 22.4 lt
So, 67.2 lt mole
and cylinder is with fixed capacity
So volume is constant means isochoric process
Option 1)
