A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The 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. (See sketch at right.) 1 atm pressure piston cylinder From previous experiments, this chemical reaction is known to absorb 352. kJ of water bath gases energy. The temperature of the water bath is monitored, and it is determined from this data that 220. kJ of heat flows out of the system during the reaction.
