In a diesel engine, the piston compresses air at 305 K to a volume that is 0.0624 of the original volume and a pressure that is 48.5 times the original pressure. What is the temperature of the air after the compression?

Answer 1

Use the fact that PV/T remains constant, if T is measured in degrees K.

P1*V1/T1 = P2*V2/T2

T2/T1 = (P2/P1)*(V2/V1)
= (48.5)*(0.0624)

You know what T1 is. Solve for T2
