Heat Transfer

Front

What is conduction?

Back

Conduction is the type of heat transfer that occurs through direct contact of molecules or particles with each other.

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, which can occur through space without the need for a medium.

Front

How does heat transfer occur from a warmer object to a cooler object?

Back

Heat always transfers from a warmer object to a cooler object until thermal equilibrium is reached.

Front

What happens to the temperature of an ice cube placed in warm water?

Back

The temperature of the ice cube increases as it absorbs heat from the warm water, causing it to melt.

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 pot of hot soup.

Front

What is an example of convection in everyday life?

Back

An example of convection is the warm air rising and cool air sinking in a room, creating a circulation of air.

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, even when you are not in direct contact with it.

Front

What is thermal equilibrium?

Back

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

Front

What is the role of insulation in heat transfer?

Back

Insulation reduces heat transfer between objects, helping to keep heat in or out of a space.
