1.	Graph of specific heat at constant volume for a monoatomic gas is ____
Answer» SOLUTION :ACCORDING to first law of thermodynamics , `DELTAQ=DeltaU+PDeltaV` If `DeltaQ` is absorbed heat at constant volume `DeltaV=0` `THEREFORE C_V=((DeltaQ)/(DeltaT))V=((DeltaU)/(DeltaT))V=(DeltaU)/(DeltaT)` For an ideal monoatomic gas, `(DeltaU)/(DeltaT)=3/2 R, C_V=3/2R`
