Thermal Energy Flashcard

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total energy of all the particles in an object.

Front

What are the three methods of heat transfer?

Back

Conduction, Convection, and Radiation.

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 and gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, which can occur in a vacuum.

Front

How does a space heater warm a room?

Back

A space heater warms a room primarily by convection currents within the room.

Front

What happens to thermal energy when you hold a cold glass?

Back

Thermal energy transfers from your warm hand to the cold glass.

Front

What is an example of conduction?

Back

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

Front

What is an example of convection?

Back

An example of convection is boiling water, where hot water rises and cooler water sinks.

Front

What is an example of radiation?

Back

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