Conduction, Convection, & Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) due to differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

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

Back

Conduction.

Front

What type of surface is a good emitter of radiation?

Back

A dark, matte surface.

Front

What happens to heat transfer when two objects are at the same temperature?

Back

No heat transfer occurs between them.

Front

What is an example of convection in everyday life?

Back

Boiling water, where hot water rises and cooler water sinks.

Front

How does a thermos reduce heat transfer?

Back

A thermos uses insulation to minimize conduction, convection, and radiation.

Front

What is the primary method of heat transfer from the Sun to the Earth?

Back

Radiation.

Front

What is the relationship between temperature and heat transfer?

Back

Heat transfers from areas of high temperature to areas of low temperature.
