Explain the meaning of thermal energy transfer and give specific examples of conduction, convection, and radiation.

Answer 1

Answer:

Thermal energy transfer involves the transfer of internal energy. The three types of thermal energy transfer are conduction, convection and radiation. ... Those are both good examples of convection, the movement of warm particles from warmer to cooler locations, Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas. Radiation is the transfer of thermal energy through thermal emission.

Answer 2

Answer:

thermal energy: the part of total internal energy that can be transferred (a portion of the kinetic energy)

heat is the thermal energy that flows from one substance to another due to a temperature difference.  

Thermal energy is measured in temperature change.

Thermal energy transfer stops when thermal equilibrium is achieved (Both substances at the same temperature).

conduction: Transfer of thermal energy through a solid object like heat transferring up a metal spoon from a hot cup of coffee.

convection: the transfer of thermal energy due to the movement of a liquid or gas caused by differences in temperature. Only in a fluid (liquid or gas). Breezes, ocean currents.

radiation: Transfer energy with or without matter. Warming from the Sun, microwave oven.
