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 through the movement of fluids (liquids and gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light, and does not require a medium to travel through.

Front

How does heat transfer occur when a cold metal spoon is placed in hot soup?

Back

The heat from the soup is conducted through the spoon, making the spoon warmer.

Front

What happens to warm air in a room?

Back

Warm air rises because it is less dense than cooler air, leading to convection currents.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is when a metal pot gets hot on a stove.

Front

What is an example of convection in everyday life?

Back

An example of convection is the circulation of warm air from a heater in a room.

Front

What is an example of radiation in everyday life?

Back

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

Front

What is the primary method of heat transfer in liquids?

Back

Convection is the primary method of heat transfer in liquids.

Front

What is the direction of heat flow when ice melts in water?

Back

Heat flows from the water to the icecap.
