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

Options

A. initial internal energy must be equal to the final internal energy
B. the work done on the system is zero
C. the work done by the system is zero
D. the initial temperature must be equal to final temperature

Answer

A, D

Explanation

Here n = constant so if `P_(2) = P_(1)` and `V_(2) =V_(1)` then `T_(2) = T_(1)`
Also work done by the system may be zero or may not be zero.
