The energy of motion

• kinetic energy

• potential energy

• electromagnetic energy

• wiggle energy

A measure of the kinetic energy of particles

• temperature

• potential energy

• count

• pressure

When heat energy is added to a substance and there is no change in state

• kinetic energy increases, particles move farther apart, temperature increases, and substance expands

• kinetic energy decreases, particles move closer, temperature decreases, and substance contracts

• kinetic energy increases, particles move farther apart, temperature decreases, and substance expands

• kinetic energy decreases, particles move farther apart, temperature decreases, and substance contracts

When heat energy is removed from a substance and there is no change in state

• kinetic energy increases, particles move farther apart, temperature increases, and substance expands

• kinetic energy decreases, particles move closer, temperature decreases, and substance contracts

• kinetic energy increases, particles move farther apart, temperature decreases, and substance expands

• kinetic energy decreases, particles move farther apart, temperature decreases, and substance contracts
