Question

The total pressure in an 11.4 L automobile tire is 45.0 psi at 16.0 ∘C. How much does the pressure in the tire rise if it warms to a temperature of 39.0 ∘C and the volume remains at 11.4 L

Answer 1

Answer:

48.58 psi

Explanation:

V1 = 11.4 L, P1 = 45 psi, T1 = 16 degree C = 16 + 273 = 289 K

T2 = 39 degree C = 39 + 273 = 312 K

Volume remains constant

Use P1 / T1 = P2 / T2

As the volume is constant, let the pressure is P2.

45 / 289 = P2 / 312

P2 = 45 x 312 / 289 = 48.58 psi
