Question

During heat transfer, thermal energy always moves in the same direction: A. COLDHOT B. HOT COLD C. No movement D. HOTHOT

Answer 1

Thermal energy during heat transfer always moves from a higher-temperature object to a lower-temperature object, as per the second law of thermodynamics.

Step-by-step explanation:

When considering heat transfer, energy typically moves from a higher-temperature object to a lower-temperature object. This movement is adequately described by the laws of thermodynamics, particularly the second law of thermodynamics, which states that heat transfer flows from a hotter object to a cooler one and that heat energy, in any process, is lost to available work in a cyclical process. For example, in the scenario of heating food in a pot on a stove, the energy in the form of heat is transferred from the hot stove element (higher temperature) to the pot and its contents (lower temperature).

Answer 2

Answer: Option (B) is the correct answer.

Step-by-step explanation:

Thermal energy is defined as the energy present within the molecules of a substance.

Also, when two objects that have different temperature and they are in contact with each other then heat will always flow from hot object to cold object.

For example, if a metal spoon is placed in a hot cup of coffee then heat will flow from hot coffee to the metal spoon.

Therefore, we can conclude that during heat transfer, thermal energy always moves in the same direction: HOT COLD.
