Heat: Transfer of Thermal Energy

Front

What is a substance with a high heat capacity?

Back

Water is a substance with a high heat capacity, meaning it can absorb a lot of heat without a significant change in temperature.

Front

What type of thermal energy transfer warms us from a campfire?

Back

Radiation is the type of thermal energy transfer that warms us from a campfire.

Front

How does a light keep food warm?

Back

A light keeps food warm by transferring thermal energy through radiation.

Front

What is the transfer of thermal energy that heats a metal spoon in hot liquid?

Back

Conduction is the transfer of thermal energy that causes a metal spoon in hot liquid to get hot.

Front

What is a substance with a high heat capacity better at?

Back

A substance with a high heat capacity is a better insulator of thermal energy.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of thermal energy in the form of electromagnetic waves, such as light.

Front

Give an example of conduction in everyday life.

Back

An example of conduction is when you touch a hot stove and feel the heat transfer to your hand.

Front

Give an example of convection in everyday life.

Back

An example of convection is when warm air rises and cool air sinks, creating a breeze.
