State the combined gas law using a sentence and an equation.

Explanation:

The combined gas law is a combination of the Boyle's law, Charles' law and Gay-Lussac's Law hence showing the relationship between temperature, pressure and volume - this law states that the relationship between the product of the temperature, pressure and volume is equal to a constant.

The combined gas law can be represented with the equation below

P₁V₁/T₁ = P₂V₂/T₂

where P₁ is the initial pressure

V₁ is the initial volume

T₁ is the initial temperature (in kelvin)

P₂ is the final pressure

V₂ is the final volume

T₂ is the final temperature (in kelvin)

i think it's letter a.
