Conduction, Convection, or Radiation?

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one, like when you touch a hot stove.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm air rises while cool air sinks, creating a cycle of heat transfer.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium, so heat can be transferred through empty space, like the Sun warming the Earth.

Front

Give an example of conduction.

Back

An example of conduction is burning your hand when touching a hot pan.

Front

Give an example of convection.

Back

An example of convection is hot air rising and cooler air falling.

Front

Give an example of radiation.

Back

An example of radiation is standing by a campfire to get warm.

Front

How does heat transfer occur in a pot of soup on the stove?

Back

Heat is transferred through conduction from the stove to the pot and then to the soup.

Front

What happens to the temperature of water left out overnight?

Back

The water and the air will be the same temperature in the morning.

Front

What is the main difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What type of heat transfer occurs when you feel warmth from the Sun?

Back

The warmth from the Sun is an example of radiation.
