Conduction, Convection, Radiation

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is convection?

Back

Convection is the transfer of thermal energy in a fluid (liquid or gas) by the movement of warm and cool fluids.

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 to travel.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon becoming hot after being left in a pot of hot soup.

Front

What is an example of convection?

Back

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

Front

What is an example of radiation?

Back

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

Front

What is insulation in the context of heat transfer?

Back

Insulation is a material or method that reduces the transfer of heat, preventing heat loss or gain.

Front

How does heat transfer occur in a solid?

Back

In solids, heat transfer occurs primarily through conduction as particles vibrate and pass energy to neighboring particles.

Front

How does heat transfer occur in fluids?

Back

In fluids, heat transfer occurs through convection as warmer, less dense fluid rises and cooler, denser fluid sinks.

Front

What is the role of temperature difference in heat transfer?

Back

Heat transfer occurs from areas of higher temperature to areas of lower temperature until thermal equilibrium is reached.
