Chapter 6: States of Matter Lesson 2: Changes in States

What happens to kinetic energy when particles move faster?

• The kinetic energy decreases

• The kinetic energy stays the same

• The kinetic energy increases

• The kinetic energy is removed

What happens to kinetic energy when particles move slower?

• The kinetic energy increases

• The kinetic energy stays the same

• The kinetic energy decreases

• The kinetic energy is removed

What is the energy an object has due to its motion?

• Temperature

• Kinetic energy

• Potential energy

• Thermal energy

What is a measure of the average kinetic energy of particles in an object?

• Kinetic energy

• Potential energy

• Temperature

• Evaporation

What happens at high temperature?

• High movement of particles → High kinetic energy

• Low movement of particles → Low kinetic energy

• Particles move slower

• Particles stay in place

What happens at low temperature?

• High movement of particles → High kinetic energy

• Low movement of particles → Low kinetic energy

• Particles move faster

• Potential energy increases

What is the stored energy due to interactions between particles or objects?

• Condensation

• Kinetic energy

• Potential energy

• Deposition

What happens to potential energy when particles or objects get farther apart?

• It increases

• It decreases

• It stays the same

• It is removed

What happens to potential energy when particles or objects get closer together?

• It increases

• It decreases

• It stays the same

• It is removed

What is the total kinetic and potential energies of particles?

• Evaporation

• Temperature

• Thermal energy

• Freezing
