A balloon has a volume of 18.0-L at a pressure of 87.6 kPa. What will be the new volume when the pressure is 48.2 kPa?

32.71 L

Explanation:

We can solve this question using Boyle's law of ideal gas. The law states that the volume and pressure are inversely proportional when the temperature is constant. At first, the volume is 18L (V1) and the pressure is 87.6 kPa (P1). Then the pressure changed into 48.2 kPa (P2). We are asked to find the volume (V2).

The calculation will be:

P1 * V1 = P2 * V2

87.6 kPa * 18L = 48.2 kPa * V2

V2 = 87.6 kPa * 18L / 48.2 kPa

V2=32.71 L
