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

Give an example of conduction in everyday life.

Back

An example of conduction is an iron smoothing out wrinkles in clothes by transferring heat directly to the fabric.

Front

What is convection?

Back

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

Front

Give an example of convection in everyday life.

Back

An example of convection is the warm air rising and cool air sinking in a room, creating a circulation pattern.

Front

What is radiation?

Back

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

Front

Give an example of radiation in everyday life.

Back

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

Front

How does heat transfer through conduction occur in metals?

Back

In metals, conduction occurs as free electrons move and transfer kinetic energy to neighboring atoms.

Front

What is the role of temperature difference in conduction?

Back

A greater temperature difference between two objects enhances the rate of heat transfer through conduction.

Front

What is the best example of conduction?

Back

An egg cooking in a frying pan is a classic example of conduction.

Front

How does convection differ from conduction?

Back

Convection involves the movement of fluids to transfer heat, while conduction involves direct contact between materials.
