For an ideal gas of fixed amount, the initial pressure and volume are equal to the final pressure and volume

Options

A. The initial temperature must be equal to the final temperature
B. The initial internal energy must be equal to the final internal energy .
C. The het heat given to an ideal gas in the process must be zero
D. The net work done by an ideal gas in the process may be zero

Answer

A, B, D

Explanation

`T = (PV)/(nR)`
`:.` initial and final temperature are equal
`DeltaQ = DeltaW +DeltaU`
as `U = (nfRT)/(2) :. U_("initial") = U_("final")`.
So `DeltaU = 0` and `DeltaQ` may be `0`
Also the net work done by an ideal gas in the process may be zero.
