Convection, Conduction, Radiation Practice

Front

What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself. Warm fluid rises while cooler fluid sinks, creating a cycle.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. Heat moves from the hotter object to the cooler one.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur through empty space.

How does heat transfer from a fire to a marshmallow when roasting it?

Back

Heat from the fire is radiated to the marshmallow.

Front

What happens to air in a room when it is heated?

Back

The warm air rises, and cooler air moves in to take its place, creating convection currents.

Front

What is an example of conduction?

Back

Touching a hot metal spoon that has been in a pot of boiling water.

Front

What is an example of convection?

Back

The attic is warmer than the basement due to the rising warm air.

Front

What is an example of radiation?

Back

The Sun heating the Earth.

Front

What is the direction of heat transfer?

Back

Heat transfers from an area of high temperature to an area of low temperature.

Front

What is the role of fluids in convection?

Back

Fluids (liquids and gases) are essential for convection as they allow for the movement of warmer and cooler areas.
