A student states Boyle’s law as follows: ""The volume of a gas is inversely proportional to its pressure."" How is this statemen
lord [1]

The statement of Boyle's law as given by the student is incorrect.

The correct statement of Boyle's law is stated below-

Boyle's law states that at constant temperature (in kelvin), the pressure of a gas is inversely proportional to the volume occupied by the gas. Therefore, with increase in pressure of the gas the volume of the gas decreases whereas with decrease in pressure of the gas, the volume of the gas increases.

The formula of Boyle's law-

                                            P ∝ 1/V

Therefore by solving this equation, we can say state that,

                                            P₁V₁= P₂V₂

where,

P₁= first pressure

P₂= second pressure

V₁= first volume

V₂= second volume
