Thermal Energy and Heat Transfer

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which is related to its temperature.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

Front

Define conduction.

Back

Conduction is the transfer of heat through a solid material without any movement of the material itself, typically occurring through direct contact.

Front

Define convection.

Back

Convection is the transfer of heat through a fluid (liquid or gas) caused by the movement of the fluid itself, often resulting in the circulation of the fluid.

Front

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur through empty space.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of hot soup.

Front

What is an example of convection in everyday life?

Back

An example of convection is the warm air rising from a heater and circulating throughout a room.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling the warmth of the sun on your skin.

How does a wet suit help a diver?

Back

A wet suit helps a diver retain thermal energy by providing insulation, reducing heat loss to the surrounding water.
