Thermal Energy Transfer

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when faster-moving particles collide with slower-moving ones, transferring energy.

Front

What are the three types of thermal energy transfer?

Back

Conduction, Convection, and Radiation.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the condition where two substances in physical contact exchange no heat energy because they are at the same temperature.

Front

How does heat energy reach the Earth from the Sun?

Back

Heat energy from the Sun reaches the Earth through radiation.

Front

What happens to particles as they cool down?

Back

As particles cool down, they slow down and move less energetically.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light and heat, without the need for a medium.

Front

Give an example of conduction in everyday life.

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

Give an example of convection in everyday life.

Back

An example of convection is boiling water, where hot water rises and cooler water sinks, creating a circular motion.

Front

Give an example of radiation in everyday life.

Back

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