V-T diagram for n mol monoatomic gas is ...

V-T diagram for n mol monoatomic gas is given below

Choose the correct statement"

A

`|(DeltaQ_(1to2))/(DeltaQ_(3to4))|=1/2`

B

`|(DeltaQ_(1to2))/(DeltaQ_(2to3))|=5/3`

C

Work done in cyclic process is `DeltaW=(nRT_(0))/2`

D

There are only adiabatic and isochoric processes are involved

Text Solution

Verified by Experts

The correct Answer is:
B, C

`(A) |(DeltaQ_(1to2))/(DeltaQ_(3to4))|=|(NC_(P)DeltaT_(1to2))/(NC_(P)DeltaT_(3to4))|=(T_(0))/(T_(0)//2)=2`
(B) `|(DeltaQ_(1to2))/(DeltaQ_(2to3))|=|(NC_(P)DeltaT_(1to2))/(NC_(V)DeltaT_(2to3))|=(C_(P))/(C_(V))=5/3`
(C) `W_("Cycle")=P_(0)V_(0)=nR [(T_(0))/2]`[Using point no. 4]
(D) Wrong as no adiabatic process is involved.
