Energy Transformation Video Lesson

What energy transformation occurs when a candle is lit?

• Thermal energy to chemical energy

• Chemical energy to thermal energy

• Light energy to chemical energy

• Kinetic energy to thermal energy

How does cooking an egg demonstrate energy transformation?

• Light energy is converted into chemical energy, changing the egg's color.

• Kinetic energy from stirring changes the egg's texture.

• Thermal energy causes chemical changes in the egg's proteins.

• Electrical energy from the stove directly creates new chemical compounds.

What is the primary energy transformation that occurs during photosynthesis?

• Chemical energy is converted into light energy.

• Thermal energy is converted into kinetic energy.

• Light energy from the sun is converted into chemical energy.

• Elastic potential energy is converted into gravitational potential energy.

When an archer pulls back a bowstring, what energy transformation is primarily occurring?

• Gravitational potential energy is converted to kinetic energy.

• Kinetic energy from the archer's arm is stored as elastic potential energy in the bowstring.

• Chemical energy is converted to thermal energy.

• Light energy is converted to chemical energy.
