Thermal Energy Concepts and Applications

The video tutorial from Lighthouse Lab explains thermal energy, its effect on temperature, and how it moves from hot to cold. It includes experiments with water temperatures and a metal rod to demonstrate heat transfer. The tutorial concludes with a summary of the key concepts.

What is thermal energy related to in terms of particle behavior?

• The color of the object

• The speed of particle movement

• The size of the particles

• The shape of the object

Which cup of water contains the most thermal energy?

• Cup B with warm tap water

• All cups have the same thermal energy

• Cup A with icy water

• Cup C with hot water from a kettle

How does thermal energy move in matter?

• It does not move

• In a circular motion

• From hot to cold

• From cold to hot

In the metal rod demonstration, which candle is expected to fall first?

• The candle closest to the heat source

• The candle in the middle

• The candle farthest from the heat source

• All candles fall at the same time

What happens to an object when it is heated?

• It gains thermal energy

• Its temperature decreases

• It changes color

• It loses thermal energy
