A helium balloon has a pressure of 0.2 kPa and a volume of 15 L. If the pressure increases to 0.5 kPa, what volume will the balloon have?

1.5 L

6.0 L

0.007 L

37.5 L

6.0 L

Explanation:

For this question, we can use

P1*V1 = P2 * V2

where

P1 (initial pressure) = 0.2 kPa

V1 (initial volume) = 15L

P2 (final pressure) = 0.5 kPa

V2 (final volume) = ?

Since we are trying to find final volume, we can rearrange the equation to make V2 the subject.

V2 = (P1 * V1) / P2

V2 = (0.2 * 15) / 0.5

V2 = 6 L
