Heat Transfer

Front

What is heat transfer?

Back

The process of thermal energy moving from one object or substance to another due to a temperature difference.

Front

What are the three main types of heat transfer?

Back

Conduction, convection, and radiation.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves, such as infrared radiation, without the need for a medium.

Front

How do thermoses minimize heat transfer?

Back

Thermoses minimize heat transfer by reducing conduction and radiation through insulation.

Front

What is an example of conduction in everyday life?

Back

When you touch a hot stove and feel the heat in your hand.

Front

What is an example of convection in a home?

Back

Warm air rising in a house, creating a circulation of air.

Front

What is an example of radiation?

Back

Feeling the warmth of the sun on your skin.

Front

What happens to the temperature of a cold drink in a hot room?

Back

The drink gets warmer as heat transfers from the air to the drink.
