The water heats up and has a rise in temperature because the zinc metal is
*
lower in thermal potential energy
higher in thermal potential energy
equal in potential energy
none of the above
In the end, after the zinc and water have been in contact for enough time, the thermal potential energy of the system and surroundings is
*
not the same
the same
The zinc metal is at a higher potential energy than the surroundings at the beginning of the experiment.
*
True
False
Once the hot zinc metal is added to the water the temperature of the zinc will
*
increase
decrease
The process for the surroundings is
*
exothermic
endothermic
