Energy Transfer

What is the law of conservation of energy?

• Energy can be created and destroyed.

• Energy can only be created, not destroyed.

• Energy cannot be created or destroyed, only transformed from one form to another.

• Energy is always constant and cannot change forms.

What is sound energy?

• Sound energy is the energy produced by vibrating objects, which creates sound waves.

• Sound energy is the energy that is stored in the form of heat.

• Sound energy is the energy that comes from the movement of electrons.

• Sound energy is the energy that is released during chemical reactions.

What is an example of a device that uses electric currents to move energy?

• A toaster

• A candle

• A wind turbine

• A battery

What is potential energy?

• The energy of an object in motion.

• The energy stored in an object due to its position or state.

• The energy released during a chemical reaction.

• The energy required to change the temperature of an object.

What is energy transfer?

• The process of moving energy from one place to another or from one form to another.

• A method of storing energy for future use.

• The conversion of energy into mass.

• The process of losing energy to the environment.

What powers computers?

• Solar energy

• Batteries

• Electricity

• Wind energy

What happens to a book left in the sun?

• The book absorbs light energy from the sun, which heats it up.

• The book becomes wet from condensation.

• The book's pages turn yellow and brittle due to UV exposure.

• The book emits light energy back into the environment.

What is kinetic energy?

• Kinetic energy is the energy of an object in motion.

• Kinetic energy is the energy stored in an object at rest.

• Kinetic energy is the energy of an object due to its temperature.

• Kinetic energy is the energy released during a chemical reaction.

What is light energy?

• Light energy is a form of energy that travels in waves and can be seen by the human eye.

• Light energy is a type of energy that is only visible under certain conditions.

• Light energy is the energy produced by chemical reactions in the dark.

• Light energy is a form of energy that can only be detected by specialized instruments.

What is the relationship between light and heat?

• Light has no effect on heat.

• Light can transfer energy to objects, which can cause them to heat up.

• Light and heat are completely unrelated phenomena.

• Light only produces heat in the absence of air.
