A gas at a volume of V0 in a container at pressure P0 is compressed to one-fifth of its volume. What will be its pressure if the magnitude of its original temperature T is constant?

A. P0/5
B. 4P0/5
C. P0
D. 5P0

Correct Answer:

Option D – 5P0

Explanation

At constant T, P1 V1 = P2 V2.

Let P1 = P0 and V1 = V0, then solve accordingly.
