Question

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

Answer 1

Answer:

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
