States of matter

What is thermal energy?

• The energy of motion in particles

• The stored energy in particles

• The sum of kinetic and potential energy of particles in an object

• The energy that helps us understand states of matter

What does kinetic energy refer to?

• Stored energy

• Energy in motion

• Energy of particles at rest

• Energy that changes states of matter

What does the kinetic-molecular theory help us understand?

• The energy of motion

• The sum of kinetic and potential energy

• States of matter and their behaviors and properties

• The creation of energy

What is all matter made of according to the Kinetic-Molecular Theory?

• Large objects
