Convection, Conduction, Radiation Practice

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids and gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

Which method of heat transfer occurs through empty space?

Back

Radiation is the method of thermal energy transfer that moves through empty space.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

Give an example of convection.

Back

An example of convection is the attic being warmer than the basement due to the rising warm air.

Front

What is the primary way heat travels through liquids and gases?

Back

Convection is the primary way heat travels through liquids and gases.

Front

What happens to a gas or liquid when it is heated?

Back

When a gas or liquid is heated, it becomes less dense and rises.

Front

What is the definition of radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur through empty space.

Front

How does heat transfer from the sun to the Earth?

Back

Heat from the sun reaches the Earth through radiation.

Front

What is an example of conduction?

Back

An example of conduction is touching a hot metal bridge, where heat transfers directly from the metal to your skin.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.
