Question:

A cylinder in a car engine takes Vi = 4.50 × 10−2 m3 of air into the chamber at 30 ° C and at atmospheric pressure. The piston then compresses the air to one-ninth of the original volume (0.111 Vi) and to 20.0 times the original pressure (20.0 Pi). What is the new temperature of the air?
