Liquid propane is commonly used as a fuel for heating homes, powering vehicles such as forklifts, and filling portable picnic tanks. Consider a propane tank that initially contains 5ml of liquid propane at the environment temperature of 20 Celsius. If a hole develops in the connecting tube of a propane tank and propane starts to leak out, determine the temperature of propane when the pressure in the tank drops to 1 atm. Also determine the total amount of heat transfer from the environment to the tank to vaporize the entire propane in the tank.
