Energy Transfers

What type of energy transfer occurs during photosynthesis?

• Chemical to thermal

• Solar to chemical

• Electrical to mechanical

• Nuclear to thermal

What is the law of conservation of energy?

• Energy can be created and destroyed.

• Energy can only be created, not destroyed.

• The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

• Energy is always constant and cannot change forms.

What is electrical energy?

• Electrical energy is the energy caused by the movement of electrons.

• Electrical energy is the energy stored in chemical bonds.

• Electrical energy is the energy produced by nuclear reactions.

• Electrical energy is the energy associated with the motion of objects.

What is energy transfer?

• Energy transfer is the process of energy moving from one place or object to another.

• Energy transfer is the ability to create energy from nothing.

• Energy transfer is the process of energy being destroyed in a system.

• Energy transfer is the method of storing energy in a single location.

What is sound energy?

• Sound energy is the energy produced by vibrating sound waves.

• Sound energy is the energy produced by moving air particles.

• Sound energy is the energy stored in musical instruments.

• Sound energy is the energy generated by electrical signals.

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 associated with an object's temperature.

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

What is thermal energy?

• Thermal energy is the energy that comes from the temperature of matter.

• Thermal energy is the energy stored in chemical bonds.

• Thermal energy is the energy associated with the motion of electrons.

• Thermal energy is the energy released during nuclear reactions.
