Text Solution

Verified by Experts

For (A)
as `PV = (1)/(3)mNv_(rms)^(2) = (2)/(3)E` so in `P = (2)/(3) E, E` is transtational kinetic energy of unit volume.
For (B):
In `U = 3RT, U ` is not internal energy of one mole as for monoatomic gas `U = 3//2 nRT`
For (C): In `W = P(V_(f)-V_(t))`, w is work done in isobaric process. For (D): In `DeltaU = nC_(v)DeltaT`
`DeltaU` is change in internal energy for every process.
