Rock · Answer 1

He expected a difference due to a change in potential energy

Explanation:

He was hypothesizing that the potential energy of the water changed as the height dropped and this change in potential energy would thus result in a drop in thermal energy and thus a drop in temperature. This would then lead to a temperature difference.
