ES2 Lesson 3 Heat Transfer

Front

What is heat transfer?

Back

The movement of thermal energy from one object or substance to another.

Front

What are the three main methods 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).

Front

What is radiation?

Back

The transfer of heat through empty space via electromagnetic waves.

Front

What is temperature?

Back

A measure of how hot or cold something is.

Front

What is thermal energy?

Back

The total energy of all the particles in an object, related to temperature.

Front

What are convection currents?

Back

The circular motion of hot air rising and cold air sinking, creating a flow.

Front

How does a thermometer work?

Back

It measures temperature by expanding or contracting a liquid (like mercury) in response to heat.

Front

What happens to particles in a hot substance?

Back

They move faster and are more spread out compared to particles in a cooler substance.
