Heat Transfer Check-in

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What are the three methods of heat transfer?

Back

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

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) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, without the need for a medium.

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through it easily, such as metals.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, such as wood, wool, or paper.

How does a cold pack work on a person?

Back

Heat is transferred from the person to the cold pack, making the person feel cooler.

Front

Why does a spoon get hot when stirring hot coffee?

Back

The spoon gets hot due to conduction, as heat is transferred from the hot coffee to the spoon.

How is heat transferred from one house to another during a fire?

Back

Heat can be transferred from one house to another by radiation, causing materials like vinyl siding to warp.
