The flow of energy is described best as

From hot to cold

Energy does not flow between substances

From low energy to high energy

From cold to hot

Question 25

25.

When a hot frying pan is placed in a sink of cold water, what will happen to the molecule’s motion?

Molecules of the pan will increase motion, molecules of the water will increase motion.

Molecules of the pan will increase motion, molecules of the water will decrease motion.

Molecules of the pan will decrease motion, molecules of the water will increase motion.
