State Boyle's law and Charles law.

Explanation

Charles law : For a fixd mass of a at constant pressure, the volumne is directly proportional to represented as (at constant p and n )
or `V=KT`
or `(V)/(K)`= Constant
Boyle's law : At a given temperature the volume occupied by a fixex mass of gas is inversely proportional to its pressure.
Mathematially, the Boyle's law can be written as
`V alpha (1)/(P)`
