Heat Transfer Practice

Front

What is heat transfer?

Back

The process of thermal energy moving from one object or substance to another due to a temperature difference.

Front

What are the three main types of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

Define conduction.

Back

A type of heat transfer that occurs through direct contact between materials.

Front

Define convection.

Back

A type of heat transfer that occurs through the movement of fluids (liquids or gases) due to differences in temperature and density.

Front

Define radiation.

Back

A type of heat transfer that occurs through electromagnetic waves, such as infrared radiation, without the need for a medium.

Front

What happens to heat transfer when two objects are at the same temperature?

Back

There is no heat transfer between the objects; they are in thermal equilibrium.

Front

How does a curling iron curl hair?

Back

It uses conduction to transfer heat from the iron to the hair.

Front

What type of heat transfer causes water to boil?

Back

Convection, as the heat is transferred through the movement of water.

Front

Why do your feet burn on hot sand?

Back

Because of conduction, as heat is transferred from the hot sand to your feet.

Front

What is thermal equilibrium?

Back

A state where two objects in contact reach the same temperature and no heat transfer occurs.
