When pressure (P) of a gas is increased, while maintaining the temperature constant, the volume (V) of the gas decreases. What is the relation between pressure and volume of the gas?
Inversely proportional if PV = constant
When the temperature is constant, an increase in pressure (P) results in a decrease in volume (V).
Hence, they are inversely related.
Hence, they will be inversely proportional if PV = constant.
