A

internal energy increases

B

enthalpy increases

C

enthalpy reduces to zero

D

enthalpy remains unchanged

Text Solution

Verified by Experts

The correct Answer is:
D
During isothermal expansion of an ideal gas
`DeltaT=0`, `DeltaU=0`
`H=U+PV` or `DeltaH=DeltaU+Delta(PV)`
`=DeltaU+nRDeltaT=0+0`
