Forms of Energy Practice

____________ energy is transferred when gasses, solids, and liquids change into a different state.

• chemical

• radiant

• mechanical

• heat

__________ energy is released from a substance when transformed into a new substance during a chemical reaction.

• chemical

• radiant

• mechanical

• heat

What type of energy is used to cook food in an oven?

• Thermal

• solar

• nuclear

• mechanical

This type of energy is caused by the vibrations of particles through a medium. 

• nuclear
• electrical
• sound
• mechanical

This type of energy is the kinetic energy of the particles (the faster the particles move, the higher the temperature is)

• electrical
• mechanical
• thermal
• sound

This energy is waves caused by the vibration of electrically charged particles; examples are visible light and x-rays.

• radiant

• thermal

• chemical

• nuclear

This type of energy is the sum of both the kinetic and potential energy. This is the energy of movement OR the stored energy that will cause movement.

• mechanical

• electrical

• sound

• chemical

What is the Law of Conservation of Energy?

• All matter is made of particles that are in constant motion.
• Energy can only be created when a force acts on an object. 
• Energy cannot be created or destroyed, but it can be transformed.
• Heating an object creates energy and cooling an object destroys energy. 

The toy oven shown uses a lamp to bake small cakes. What types of energy does the toy oven use to bake the cakes?

• Light and sound

• Electrical and thermal

• Thermal and mechanical

• Mechanical and electrical

Sound energy is present when...

• an object vibrates
• energy is created
• energy is destroyed
