A certain quantity of an ideal gas initially at temperature `T_(0)`.pressure `P_(0)`, and volume `V_(0)` is compressed to one-half of its initial volume. As shown below, the process may be adiabatic (process 1), isothermal (process 2), or isobaric (process 3).

Which of the following is true for the mechanical work done on the gas?

A

It is greatest for process1

B

It is greatest for process 3.

C

It is the same for processes 1 and 2 and less for process 3.

D

It is the same for processes 2 and 3 and less for process 1
