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 when a metal spoon gets hot after being placed in a pot of boiling water.

Front

What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself.

Front

Describe a common example of convection.

Back

A common example of convection is the rising and falling of water in a pot when heating soup.

Front

What is radiation?

Back

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

Front

How does the sun heat the Earth?

Back

The sun heats the Earth through radiation, as sunlight travels through the vacuum of space.

Front

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

Back

The primary way heat travels through liquids and gases is through convection.

Front

What happens to the temperature of a substance when it absorbs heat?

Back

When a substance absorbs heat, its temperature typically increases.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

How does a heat pack warm cold feet?

Back

A heat pack warms cold feet through conduction, as heat transfers from the pack to the feet.
