Air is trapped in a cylinder fitted with a piston that occupies 150.5 mL at 1.12 atm pressure. What is the new volume when the piston is depressed, increasing the pressure by 15%?

Respuesta :

Answer:

New volume V2 = 120.4 ml

Explanation:

Given:

Pressure P1 = 1.12 atm

New pressure P2 = 1.12[1+0.25] = 1.4 atm

Old volume V1 = 150.5 ml

Find:

New volume V2

Computation:

P1V1 = P2V2

(1.12)(150.5) = (1.4)(V2)

V2 = 120.4 ml

New volume V2 = 120.4 ml
