Heat Transfer

Front

What is the difference between heat and temperature?

Back

Heat measures the total energy of all the molecules in an object, while temperature measures the average kinetic energy of the molecules.

Front

What process warms the soil when sunlight reaches it?

Back

Radiation from the sun warms the soil.

Front

What happens when an ice cube is placed in warm water?

Back

Energy in the form of heat is transferred from the water to the ice cube by conduction.

Front

What is conduction?

Back

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

Front

What is NOT true about conduction?

Back

Conduction cannot transfer energy through empty space.

Front

What is temperature?

Back

Temperature is the measure of average kinetic energy of all the particles within an object.

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 in the form of electromagnetic waves, such as light.

Front

How does heat transfer occur in a vacuum?

Back

Heat transfer in a vacuum occurs only through radiation, as there are no particles to conduct or convect heat.

Front

What is an example of conduction?

Back

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