A mixture of gaseous reactants is put into a cylinder, where a chemical reaction turns them into gaseous products. The cyllnder 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.) The temperature of the water bath is monitored, and it is determined from this data that 194 . kJ of heat flows into the system during the reaction. The position of the piston is also monitored, and it is determined from this data that the system does 392 . kJ of work on the piston during the reaction.
