Five lbs of propane is contained in a closed, rigid tank initially at 80 lbf/in.2, 150°F. Heat transfer occurs until the final temperature in the tank is 0°F. Kinetic and potential energy effects are negligible. Determine the amount of energy transfer by heat, in Btu. i292.5 Btu

A mixtu. - gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The 1 atm pressure cylinder has a piston that moves in or out, as necessary, to keep a constant pressure on the mixture of 1 atm. The cylinder is also submerged in a large insulated water bath.
