Thermal Energy - 1st

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 conduction?

Back

Conduction is the method of heat transfer that occurs through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves and does not require matter.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.

Front

How does heat transfer from hot to cold?

Back

Heat naturally flows from areas of higher temperature to areas of lower temperature until thermal equilibrium is reached.

Front

What is an example of conduction?

Back

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

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking, creating a breeze.

Front

What is an example of radiation?

Back

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

Front

What is the role of thermal insulators?

Back

Thermal insulators are materials that reduce the transfer of heat, keeping hot things hot and cold things cold.
