If #32 L# of a gas at room temperature exerts a pressure of #64 kPa# on its container, what pressure will the gas exert if the container's volume changes to #24 L#?
The decrease in volume causes the pressure to increase to 85 kPa.
This is an example of Boyle's law, which states that the pressure and volume of a gas kept at constant temperature vary inversely, meaning that if the volume increases, the pressure will decrease and vice versa. The equation to use is
Rearrange the equation to isolate
As expected from Boyle's law, when the volume decreased from 32 L to 24 L, the pressure increased from 64 kPa to 85 kPa.
