The internal energy of a system remains ...

The internal energy of a system remains constant when it undergoes
(i) a cyclic process
(ii) an isothermal process
(iii) an adiabatic process
(iv) any process in which the heat given out by the system equal to the work done on the system

A

a cyclic process

B

an isothermal process

C

an adiabatic process

D

any process in which the heat given out by the system is equal to the work done on the system

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
`Q= DeltaU + W` and `DeltaU = nC_(v)DeltaT`
`DeltaU` can be zero if `DeltaT` is zero or `Q - W` is zero
