Energy transformations quiz

What is the relationship between energy forms?

• Different forms of energy can be transformed into one another, but the total energy remains constant.

• Energy can be created and destroyed in different forms.

• All forms of energy are equal and interchangeable without loss.

• Energy can only be transformed from kinetic to potential energy.

Can energy change forms?

• No, energy cannot change forms.

• Only some types of energy can change forms.

• Yes, energy can change forms.

• Energy can only be created, not changed.

What happens to energy in a closed system?

• Energy is created and destroyed.

• Energy is conserved and can only change forms.

• Energy can be lost to the surroundings.

• Energy can be transformed into matter.

What is light energy?

• Light energy is the energy that is visible to the human eye and is produced by light sources.

• Light energy is a form of energy that cannot be seen by the human eye.

• Light energy is the energy stored in chemical bonds of molecules.

• Light energy is the energy that comes from sound waves.

What does the term 'transform' mean in the context of energy?

• To change from one form to another.

• To create energy from nothing.
