conduction,convection,radiation flashcard

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warm fluid rises and cool fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight warming the Earth.

Front

What happens to air when it is heated?

Back

When air is heated, it becomes less dense and rises, creating convection currents.

Front

What is a good example of conduction?

Back

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

Front

What is a good example of convection?

Back

A good example of convection is boiling water, where hot water rises to the top and cooler water sinks.

Front

What is a good example of radiation?

Back

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

Front

What is the best conductor of heat?

Back

The best conductor of heat is typically metals, with copper being one of the best.

Front

Where is the hottest air located in a heated room?

Back

The hottest air in a heated room is usually near the ceiling.

Front

What type of energy is involved in heating water on a stove?

Back

The type of energy involved in heating water on a stove is thermal energy.
