Describe Charle’s Law and Boyle’s Law.

Explanation:

Boyle's law can be stated as the "volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant". It is mathematically expressed as;

    P1 V1  = P2 V2

P1 is the initial pressure

V1 is the initial volume

P2 is the final pressure

V2 is the final volume

Charles's law states that the volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant.

It is mathematically expressed as;

               =  

V and T are volume and temperature respectively

1 and 2 are the initial and final states

gravititional force is a force that is acting around you, it is non-contactable and it is a force that pulls you to the core of the earth.
