Question

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

Answer 1

V₂ = 30 L

Step-by-step 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
