Boyle’s law states that absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remains unchanged within a closed system.
i.e. P ∝ 1/v
[Keeping temp. and amt. of gas fixed] Charles’s law
Law of volumes: - V ∝ T [Given pressure and amount of gas remains constant] These laws are not applicable to real gases since in real gases size of particles is not negligible, collisions of particles are not elastic and there are attractive forces between particles.
