O THERMOCHEMISTRY
Understanding the definitions of heat and work
A mixture of 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. (See sketch at right.)
The temperature of the water bath is monitored, and it is determined from this data that 259. 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
piston does 322. kJ of work on the system during the reaction.
