Convection, Conduction, Radiation Practice

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm fluid rises while cool fluid sinks, creating a circulation pattern.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one.

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

Give an example of convection.

Back

An example of convection is the movement of warm air rising and cool air sinking, such as in a room heated by a radiator.

Front

Give an example of conduction.

Back

An example of conduction is a metal spoon getting hot when placed in a hot pot of soup.

Front

Give an example of radiation.

Back

An example of radiation is feeling warmth from the sun on your skin.

Front

What are the three types of heat transfer?

Back

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

Front

How does convection occur in water?

Back

In water, convection occurs when heated water becomes less dense and rises, while cooler, denser water sinks, creating a circular motion.

Front

What role does conduction play in cooking?

Back

Conduction plays a role in cooking when heat is transferred from the stove to the pot and then to the food inside.

Front

How does radiation heat the Earth?

Back

Radiation from the sun travels through space and warms the Earth’s surface when it is absorbed.
