They are all one question. A chemical reaction is run in which 469 Joules of work is done by the system and the internal energy changes by -571 Joules. Calculate q for the system. q =  Joules An automobile engine generates 2141 Joules of heat that must be carried away by the cooling system. The internal energy changes by -2670 Joules in this process. Calculate w for the engine. This represents the work available to push the pistons in this process. w =  Joules An automobile engine provides 592 Joules of work to push the pistons. In this process the internal energy changes by -2839 Joules.
