Question

Examples of how thermal energy transfer by conduction, convection, or radiation.

Answer 1

Conduction is the transfer of heat through physical contact, such as when heat is transferred from a stove burner to a pan. Convection is the transfer of heat by the movement of a fluid, like hot air rising from a fireplace. Radiation is the transfer of heat through electromagnetic waves, such as the warming of the Earth by the Sun.

Step-by-step explanation:

Conduction is the transfer of heat through stationary matter by physical contact. An example of conduction is when heat is transferred from a stove burner to the bottom of a pan which then heats up the food inside.

Convection is the transfer of heat by the movement of a fluid. A common example of convection is the way hot air rises from a fireplace.

Radiation occurs when heat is transferred through electromagnetic waves. The warming of the Earth by the Sun is an example of radiation, as is the thermal radiation from the human body.

Answer 2

Microwave Radiation. Microwave radiation utilizes short, high-frequency waves that penetrate food, which agitates its water molecules to create friction and transfer heat. If you're heating a solid substance, this heat energy is transferred throughout the food through conduction, while liquids do so through convection.
