Question

A sample of gas at 1 atm pressure occupies 5000 m^3 . what is the volume when the pressure is increased to 50 atm?

Answer 1

a. 1000 m^3
b. 10 m^3
c. 1 m^3
d. 100 m^3

Answer 2

So as @apoorvk mentioned before, you can set up this problem by understanding that pressure and volume are proportional.

P1V1 = P2V2

Since you're looking for V2, simply rewrite the proportion.

P1 / P2 * V1 = V2 and solve!
