Heat Transfer

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when two objects at different temperatures touch each other, allowing heat to flow from the hotter object to the cooler one. Example: A burner heating the bottom of a pot.

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer, less dense areas of a fluid rise and cooler, denser areas sink, creating a circulation pattern. Example: Warm air rising near the ceiling of a room.

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium (like air or water) to transfer heat. Example: The heat from the sun reaching the Earth.

How does heat flow between two objects?

Back

Heat flows from the hotter object to the cooler object until they reach thermal equilibrium (the same temperature).

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature, resulting in no net heat transfer between them.

What is an example of conduction in everyday life?

Back

An example of conduction is when you touch a hot stove and feel the heat transfer to your hand.

Front

What is an example of convection in everyday life?

Back

An example of convection is when boiling water in a pot; the hot water rises to the top while cooler water sinks.

What is an example of radiation in everyday life?

Back

An example of radiation is feeling warmth from a campfire or the sun without being in direct contact with it.

Front

What role does air play in convection?

Back

Air acts as a fluid in convection, allowing warm air to rise and cool air to sink, creating a circulation pattern that transfers heat.

Front

What happens to the temperature of an object when it absorbs heat?

Back

When an object absorbs heat, its temperature increases as the energy causes the particles within the object to move faster.
