Question

Consider question #1. Based on the student data, the prediction was correct. Remember, heat is the transfer of energy from the high temperature object to the low temperature object until equilibrium is met and that was what happened in this case. How did this transfer of energy occur at the molecular level?

Question 1: One student in the group questioned the prediction. "How can heat energy move? There is nothing moving from the can to the cup!" How would you respond to this student?


A) Heat is transferred from one object to another object through particle collisions. The hot water had the greatest kinetic energy. Particle collisions transferred that energy from the hot water, to the can, and then to the cooler water.


B) Temperature changes due the transfer of heat energy. The hot water had the greatest heat energy. Heat was transferred from the inside of the can to the outside of the can, or into the water held in the styrofoam cup.


C) Heat energy always travels from high to low. The heat energy flowed through the water in the can, through the metal since it is a good conductor, and then out into the cooler water, raising the temperature there.


D) Because the hot water had the highest temperature, it also had the greatest stored or potential energy. That energy was shared with the cooler water until the two volumes were at the same temperature.

Answer 1

Answer:Heat is transferred from one object to another object through particle collisions. The hot water had the greatest kinetic energy. Particle collisions transferred that energy from the hot water, to the can, and then to the cooler water.

Explanation:hope this helps :)

Answer 2

A) Heat is transferred from one object to another object through particle collisions. The hot water had the greatest kinetic energy. Particle collisions transferred that energy from the hot water, to the can, and then to the cooler water.

Explanation: Did it on USA test prep and got it right. :)
