Conduction, convection, and Radiation Practice

Front

What is conduction?

Back

Conduction is the transfer of heat through a solid material without the movement of the material itself. It occurs when two objects at different temperatures are in direct contact.

What is convection?

Back

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

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation. It does not require a medium and can occur in a vacuum.

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

Back

Heat transfer occurs through conduction, as the heat from the hot soup is directly transferred to the metal spoon.

Front

What is the direction of heat flow in thermal energy transfer?

Back

Heat always flows from the hotter substance to the colder substance.

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks 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.

What is the role of insulation in heat transfer?

Back

Insulation reduces heat transfer by conduction, convection, and radiation, helping to keep heat in or out of a space.

What happens to the temperature of a substance when it absorbs heat?

Back

The temperature of the substance increases as it absorbs heat energy.

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact in solids, while convection is heat transfer through the movement of fluids.
