Heat Transfer Practice

Front

What is convection?

Back

Convection is the transfer of heat by the movement of liquids or gases, where warm areas rise and cool areas sink.

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

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight warming the Earth.

Front

Example of convection in everyday life?

Back

An example of convection is warm air rising from a heater and cool air sinking, creating a circulation of air.

Front

How do lava lamps demonstrate convection?

Back

In lava lamps, colored liquids form globs that rise when heated and sink when cooled, demonstrating convection.

Front

What happens to warm water in the ocean?

Back

Warm water rises to the surface while cooler water sinks, demonstrating convection currents.

Front

What is an example of conduction?

Back

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

Front

What is an example of radiation?

Back

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

Front

What is the role of heat lamps for baby chickens?

Back

Heat lamps provide radiation to keep baby chickens warm.

Front

What is the difference between conduction and convection?

Back

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