Heat Transfer shorter

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when two objects at different temperatures touch each other.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, allowing heat to be transferred through empty space.

Front

What happens to water when it changes from liquid to solid?

Back

Water loses energy and its temperature decreases, resulting in the formation of ice.

Front

What type of heat transfer occurs when you touch a hot stove?

Back

Conduction occurs when you touch a hot stove, as heat is transferred directly from the stove to your hand.

Front

What type of heat transfer occurs during sunbathing?

Back

Radiation occurs during sunbathing, as heat from the sun travels through space and warms your skin.

Front

What is an example of convection?

Back

An example of convection is when boiling water circulates in a pot, with hot water rising to the top and cooler water sinking.

Front

What is the main difference between conduction and convection?

Back

Conduction involves direct contact between materials, while convection involves the movement of fluids.

Front

What is an example of radiation?

Back

An example of radiation is feeling warmth from the sun on your skin, even on a cool day.

Front

What is the process of heat transfer through empty space called?

Back

The process of heat transfer through empty space is called radiation.
