What volume of air at 1 atm would have to be put into a car tire with a volume of 15 l if the pressure in the car tire is to be 30 psi

V₂ = 30 L

Explanation:

Given data:

Initial pressure = 30 psi (30 /14.696 = 2 atm)

Initial volume = 15 L

Final volume = ?

Final pressure = 1 atm

Solution;

P₁V₁ = P₂V₂

V₂ = P₁V₁  / P₂

V₂ = 2 atm .  15 L /  1 atm

V₂ = 30 L
