Thermal Energy Transformations

Front

What are the three ways heat is transferred?

Back

Radiation, conduction, and convection.

Front

True or False: Convection can take place in solids only.

Back

False, convection can take place in liquids and gases.

Front

What process transfers heat when a barefoot student steps on a hot concrete surface?

Back

Conduction.

Front

What best describes the heat transfer occurring when a student opens the top and bottom windows in a hot room?

Back

Convection.

Front

How does air travel in terms of temperature?

Back

Air travels from hot to cold.

Front

Define conduction.

Back

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

Front

Define convection.

Back

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

Front

Define radiation.

Back

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

Front

What is an example of conduction?

Back

Touching a hot stove and feeling the heat.

Front

What is an example of convection?

Back

Boiling water where hot water rises and cooler water sinks.
