Charles Law

A large electric generator is cooled by a gas that then passes through a heat exchanger and is cooled itself. One cubic meter of gas enters the heat exchanger with a temperature of 77°C. When it leaves the heat exchanger, it occupies 0.95 cubic meter. What is the temperature, in Celsius, of the gas as it leaves the heat exchanger? (Remember to convert Celsius to Kelvin when calculating, then back to Celsius.)

• 325°C

• 59.5°C

• 62.7°C

• 55.6°C
