Thermal heat transfer

Front

What is thermal heat transfer?

Back

The process of energy transfer from one body or system to another due to a temperature difference.

Front

What are the three main types of heat transfer?

Back

Conduction, convection, and radiation.

Front

Define conduction.

Back

The transfer of heat through direct contact between materials.

Front

Define convection.

Back

The transfer of heat by the movement of fluids (liquids or gases) due to differences in density.

Front

Define radiation.

Back

The transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

What happens to the density of a fluid when it is heated?

Back

The density decreases.

What is an example of conduction in everyday life?

Back

A metal spoon getting hot when stirred in hot coffee.

Front

What is an example of convection in everyday life?

Back

The rising of warm air and sinking of cool air in a room.

Front

What is an example of radiation in everyday life?

Back

Feeling warmth from the sun on your skin.

Front

How does a lava lamp demonstrate convection?

Back

The colored liquid forms globs that rise and fall as they are heated and cooled, demonstrating fluid movement.
