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 demonstration using cups of water to measure temperature differences. The tutorial concludes with an experiment showing heat transfer along a metal rod, illustrating the concept of heat moving from hot to cold.

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

• The color of the particles

• The size of the particles

• The movement of the particles

• The shape of the particles

How does the temperature of an object relate to its thermal energy?

• Temperature and thermal energy are unrelated

• Higher temperature means less thermal energy

• Higher temperature means more thermal energy

• Temperature is always constant regardless of thermal energy

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 B with warm tap water

• Cup A with icy water

What is the temperature of the water in Cup B?

• 100 degrees Celsius

• 60 degrees Celsius

• 25 degrees Celsius

• 4 degrees Celsius

In which direction does heat move?

• In a circular motion

• It does not move

• From hot to cold

• From cold to hot

What happens to the candles attached to the metal rod when it is heated?

• The candle farthest from the heat source melts first

• The candle closest to the heat source melts first

• None of the candles melt

• They all melt at the same time

What is the process called when thermal energy moves within an object?

• Conduction

• Radiation

• Heat

• Convection

What is the main takeaway about thermal energy from the video?

• Thermal energy is only present in solids

• Thermal energy moves from hot to cold

• Thermal energy is unrelated to particle movement

• Thermal energy decreases temperature

What happens to an object when it gains thermal energy?

• Its temperature decreases

• It remains the same

• Its temperature increases

• It becomes colder

What is the effect of heating an object on its thermal energy?

• It loses thermal energy

• It gains thermal energy

• Thermal energy remains constant

• Thermal energy is destroyed
