A sample of monoatomic gas undergoes a process as represented by T-V graph (if `P_(0)V_(0)=1//3 RT_(0)`) then

`(P) W_(1to2)=1/3 RT_(0)ln2" " (Q)_(1to2to3)=(RT_(0))/6 (2ln(2)+3)`
`(R) U_(1to2)=0" " (S) W_(1to2to3)=(RT_(0))/3 ln2`
Which of the following option are correct:

A

P,Q are incorrect

B

R,S are incorrect

C

P,Q,S are incorrect

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
D
`W_(1-2)=nRT_(0) ln2`
`Q_(1-2-3) =Q_(1-2)+Q_(2-3) `
`=dW_(1-2)+dU_(2-3)`
`=(RT_(0))/3ln2+nf/2 RT_(0)`
`=(RT_(0))/3 ln2 +1/3 3/2 RT_(0)`
`U_(1-2)=0`
`W_(1-2-3)=1/3 RT_(0)ln 2+0`
