Which sample of ethanol has particles with the highest average kinetic energy?

2 answers:

6 0

The second one.
Remember, temperature is the AVERAGE kinetic energy. So, looking for highest average kinetic energy means looking for highest temperature, which is 55.
Note: the amount of the substance does not determine the average kinetic energy.
