In Mayer's relation: C(P)-C(V)=R 'R'...

In Mayer's relation:
`C_(P)-C_(V)=R`
'R' stands for:

A

translational kinetic energy of 1 mol gas

B

rotational kinetic energy of 1 mol gas

C

vibrational kinetic energy of 1 mol gas

D

work done to increase the temperature of 1 mol gas by one degree

Text Solution

Verified by Experts

The correct Answer is:
D
`PV=RT` (for 1 mol gas)
`P(V+DeltaV)=R(T+1)`
From eqs. (i) and (ii)
`PDeltaV=R`
`w=R` (work done).

Assertion: C_(P)-C_(V)=R for an ideal gas. Reason: ((delE)/(delV))_(T)=0 for an ideal gas.

For a gas C_(P)-C_(V)=R in a state P and C_(P)-C_(V)=1.10 R in a state Q, T_(P) and T_(Q) are the temperatures in two different states P and Q respectively. Then

Assertion: C_(p) can be less than C_(V) . Reason: C_(p)C_(V)=R is valid only for ideal gases.
