Thermal Energy and Heat Transfer

The video tutorial from Lighthouse Lab explains thermal energy, its effect on temperature, and how it moves from hot to cold. It begins with an introduction to thermal energy, followed by a comparison of thermal energy in three cups of water at different temperatures. A demonstration using a metal rod and candles illustrates heat transfer. The video concludes with a summary of the key concepts discussed.

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

• The speed of particle movement

• The color of the object

• The shape of the object

• The size of the particles

Which cup of water contains the most thermal energy?

• All cups have the same thermal energy

• Cup C with hot water from a kettle

• Cup A with icy water

• Cup B with warm tap water

How does heat move in matter?

• It does not move

• In a circular motion

• From cold to hot

• From hot to cold

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

• The candle farthest from the heat source

• All candles fall at the same time

• The candle closest to the heat source

• The candle in the middle

What happens to an object when it is heated?

• It loses thermal energy

• Its temperature decreases

• It gains thermal energy

• It changes color
