Phase Changes & Properties of Matter

Which of the following describes a solid?

• No definite shape or definite volume, lowest intermolecular forces

• Definite volume, takes the shape of its container, no definite shape

• Definite shape and definite volume, vibrates in place and highest intermolecular forces

• Highest Kinetic Energy

What is the relationship between temperature and particle motion (kinetic energy)?

• As temperature increases, particle motion/ kinetic energy decreases

• As temperature increases, particle motion/kinetic energy increases

• As temperature decreases, particle motion / kinetic energy decreases

• As temperature decreases, particle motion / kinetic energy increases
