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
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.)
From previous experiments, this chemical reaction is known to release 107. kJ of energy.
The position of the piston is monitored, and it is determined from this data that the system does 306. kJ of work on the
piston during the reaction.
Is the reaction exothermic or endothermic?
Does the temperature of the water bath go up or
down?
Does the piston move in or out?
Does heat flow into or out of the gas mixture?
How much heat flows? Round your answer to 3
significant digits.
