An ideal gas expands according to the law `PV^(3//2)`=constant We conclude that

A

the adiabatic exponent of the gas k=1.5

B

the molar heat capacity `C=C_(V)-2R`

C

temperature increases during the process

D

such a gas is not feasible.

Text Solution

Verified by Experts

The correct Answer is:
B
`C=C_(V)+(PdV)/(ndT)`
`PV^(3//2)=k," "PV=nRT`
Find relation in V and T
`(dV)/(dT)=-(2V)/(T)`
`thereforeC=C_(V)-2R`
