A sample of monoatomic gas undergoes dif...

A sample of monoatomic gas undergoes different thermodynamic process. Q=Heat given to the gas, W=work done by the gas, U=Change in internal energy of the gas.
The sample of monoatomic gas undergoes a process as represented by P-V graph (if `P_(0)V_(0)=1//3 RT_(0)`)

`(P) W_(1to2)=1//3 RT_(0) " " (Q) Q_(1 to 2 to 3) =11//6 RT_(0)`
`(R) U_(1 to 2) =RT_(0)//2" " (S) W_(1to2to3) =1//3 RT_(0)`
Which of the following option are correct

A

P,Q,R,S are correct

B

Only P,Q are correct

C

Only R,S are correct

D

Only P,R,S correct

Text Solution

Verified by Experts

`W_(1-2)=P_(0)V_(0)=1//3 RT_(0)`
`Q_(2t- 3)=nC_(v)DeltaT=nf/2R DeltaT=f/2 2V_(0) P_(0)=fP_(0)V_(0)=RT_(0)`
`Q_(1-2)=nC_(p)DeltaT=n(f/2+1) R Delta T=5/2. P_(0)V_(0)=5/6 RT_(0)`
`W_(1-2-3)=1//3 RT_(0)`
`U_(1-2)=nC_(V)DeltaT`
`=n3/2 RT_(0)`
`=(RT_(0))/2`
