Mathematics for IGCSE & O level - Proportion (Section 1 - No. 36)
The pressure exerted by a gas on the walls of a container is inversely proportional to the volume of the container. If the volume of the container is halved, what happens to the pressure?
The pressure is halved.
The pressure doubles.
The pressure is quartered.
The pressure stays the same.
Објашњење
Pressure = k/Volume, if the volume is halved, P = k/(Volume/2) = 2k/Volume, so pressure doubles.
