Front

What is thermal energy?

Back

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

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

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 or gases) caused by differences in temperature.

Front

Define radiation.

Back

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

Front

What happens to the temperature of a substance when it absorbs heat?

Back

The temperature of the substance increases when it absorbs heat.

Front

What happens to the temperature of a substance when it loses heat?

Back

The temperature of the substance decreases when it loses heat.

Front

What is the Fahrenheit scale?

Back

The Fahrenheit scale is a temperature scale where water freezes at 32 degrees and boils at 212 degrees.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot pot of soup.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room.
