practical application of boyles law
Dear student!
According to Boyle's law: the pressure exerted by a gas held at constant temperature is inversely proportional to the volume of the gas. So, at constant temperature P V =Constant.
Hence, the best example of Boyle's law is "Syringe" as when we draw a fluid inside a syringe , the volume inside is increased making the pressure outside greater which forces the fluid into the syringe.
And hence, over all product of pressure and volume becomes constant. i.e. PV =constant for a syringe.
