Thermal Energy Flashcard

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of moving particles in a substance.

Front

What type of heat transfer occurs when warm air rises and cool air sinks?

Back

Convection.

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves, such as sunlight.

Front

How does mass affect thermal energy?

Back

Objects with more mass have more thermal energy because there are more molecules with energy in bonds.

Front

What is the primary method of heat transfer when walking on warm sand?

Back

Conduction.

Front

What is an example of convection in everyday life?

Back

Boiling water, where hot water rises and cool water sinks.

Front

What is an example of radiation?

Back

Feeling the warmth of the sun on your skin.

Front

What happens to the thermal energy of a substance when it is heated?

Back

The thermal energy increases as the particles move faster.
