A bicycle pump contains 100mL of air at 17oC and 101kPa, and this gas is compressed to 23mL with a pressure of 475kPa before the tube valve opens to admit the gas into the tube. What is the temperature of the compressed gas just before the valve opens?

T2 = (P2V2T1/P1V1), T1 = 17oC = 290oK
T2 = 475 kpa×23mL×290ok/101kpa×100mL
T2 = 313.688oK
T2 = 40.688oC is the temperature of the compressed gas
