# Three Paths on PV Diagram

APPH12-YELHQ3

A gas is taken from point $i$ to point $f$ three different times through three distinct processes.

Each process is shown above on the P-V diagram with paths labeled: A, B, and C.

Which of the following statements are CORRECT?

A

Path A is the only one that represents a momentary compression of the gas.

B

The change in internal energy between points $i$ and $f$ is the highest along path B.

C

The most work done by the gas is along path C.

D

The change in temperature between points $i$ and $f$ is the same for all three paths.
