The Concept of Thermal Energy Transfer in Boiling Water

What is thermal energy and how does it relate to the transfer of heat between boiling water and a mug?

A. Thermal energy is the energy generated in a substance when the temperature increases and molecules move faster.

B. Thermal energy is the energy produced by the collision of molecules in a heated material.

C. Thermal energy is directly proportional to the temperature of a system.

D. Thermal energy transfer stops when the water and the mug reach the same temperature.

Answer:

Which indicates that thermal energy is no longer being transferred from boiling water to a mug?

The water and the mug are the same temperature.

The water is hotter than the mug.

The mug is hotter than the water.

The water and the mug lose all thermal energy.

Thermal energy is the energy generated in a substance when there is an increase in temperature causing atoms and molecules to move at a faster speed and resulting in collisions between molecules. This energy generated from the temperature of the heated material is known as thermal energy.

Internal kinetic energy, or thermal energy, is due to the random motion of molecules within a system. The thermal energy of a system is directly proportional to its temperature. The higher the temperature of the system, the more movement there is within the molecules and, consequently, the greater the thermal energy of the system.

When boiling water is transferred to a mug, thermal energy is transferred along with the heat. The transfer of thermal energy stops when the water and the mug reach the same temperature. At this point, there is no longer a temperature difference between the two substances, leading to the cessation of thermal energy transfer.
