Question

?? Understanding the definitions of heat and work submerged in a large insulated water bath. (See sketch at night.) From previous experiments, this chemical reaction is known to release 183. J of energy The position of the piston is monitored, and it is determined from this data that the system does 273. LJ of work on the piston during the reaction. O exothermik ts the reaction exothermic or endothermic ?up O down O nelther O in ?out Does the temperature of the water bath go up or down? Does the piston move in or out? 0 out O nelther Does heat flow into or out ofthe gas mixture? How much heat flows? Round your answer to 2 significant digits kl O B 0 Type here to search 9

Explanation / Answer

Heat is released during the process

The reaction is exothermic

The temperature of the water bath will go up

The system does work on the piston, the piston move out

The heat flow out of the system

Heat flows = - 183 +273 = 90 kJ
