Question

When a gad is composed adiabatically and reversibly , the final temperature is :-
(a) dalta E=0
(b) P dalta V=0
(c) q=0
(d) q= +w

Answer 1

When an ideal gas is compressed adiabatically and reversibly, the final temperature is higher than initial temperature. As dU is positive , then temperature must be increased . So, When an ideal gas is compressed adiabatically and reversibly, the final temperature is higher than initial temperature.
