Heat Transfer: Conduction, Convection, Radiation P1

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 or 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 infrared radiation, and does not require a medium.

Front

In heat transfer, heat flows from which type of object to which type of object?

Back

Heat always flows from a hotter object to a colder object.

Front

What happens to the molecules in a substance when it is heated?

Back

The molecules move faster and spread apart, increasing the temperature of the substance.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is when a metal spoon gets hot after being placed in a hot pot of soup.

Front

What is an example of convection in everyday life?

Back

An example of convection is the warm air rising to the ceiling in a room, causing cooler air to move down.

Front

What is an example of radiation in everyday life?

Back

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

Front

How does convection affect weather patterns?

Back

Convection currents in the atmosphere can lead to the formation of clouds and storms.

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.
