Air is transferred from a 75 L tank where the pressure is 125 psi and the temperture is 288 k to a tire with a volume of 6.1 L and a pressure of 25 psi. What is the new temperture.

Answer;

= 4.68 K

Explanation;

According to the combined gas law;

P1V1/T1 = P2V2/T2

Given; P1 = 125 Psi

V1 = 75 L

T1 = 288 K

P2 = 25 PSI

V2 = 6.1 L

Therefore;

T2 = P2V2T1/P1V1

= (25*6.1 * 288) / (125*75)

= 4.6848

= 4.68 K
