LEARNING OUTCOMESLEARNING OUTCOMES
By the end of this chapter, student should able to:
1. Relate the change in state of matter to the change in heat.
2. Relate the change in heat to the change in kinetic energy of particles.
3. Explain the inter-conversion of the state of matter in term of kinetic theory of matter.

KINETIC THEORY OF MATTER
• The higher the temperature, the higher the kinetic energy of the particles.
Kinetic energy of particles increases (HEATING)
Kinetic energy of particles decreases (COOLING)
Heat energy is absorbed
Heat energy is released
