Heat Transfer

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 main types of heat transfer?

Back

The three main types 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.

Front

What is radiation?

Back

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

Why does an ice cube melt in hot liquid?

Back

Heat from the liquid transfers to the ice, causing it to melt.

Front

What happens to the temperature of water when ice is added?

Back

The temperature of the water decreases because some of the water's heat is lost to the ice.

Front

What occurs when water boils?

Back

Evaporation occurs when water boils, as it changes from liquid to gas.

Front

What is an example of conduction?

Back

Touching a hot handle and getting burned is an example of conduction.

Front

What is an example of convection?

Back

A hot air balloon rising and falling is an example of convection.
