Example Sentences

“According to Boyle’s law, if the temperature doesn’t change, pressure and volume are inversely correlated, which means that pressure changes in the environment can cause expansion or contraction of air-space cavities in the body.”

Boyle’s law states that if the temperature of a gas stays constant, then the pressure varies inversely to the volume of the gas.

For example, Boyle’s law, which links a gas’s pressure and volume, is often known in France as Mariotte’s law, after seventeenth century physicist Edme Mariotte, who discovered it independently of Anglo-Irish Robert Boyle.

Boyle’s law describes the relationship between volume and pressure.

From Textbooks • Jun. 19, 2013

Boyle’s law provided a theoretical account of how pressure could be used to produce powerful force, if one could only find a way of harnessing that force for a useful purpose.
