The document outlines learning objectives for understanding the properties and states of matter, including solids, liquids, and gases, as well as changes of state such as melting and boiling. It introduces kinetic particle theory to explain the behavior of matter under varying temperature and pressure conditions, and discusses the concept of pure substances and diffusion. Additionally, the document provides links to simulations and videos for further exploration of these topics.

1. Lesson 1:
Learning Objectives:
•State the distinguishing properties of solids,liquids and gases.
•Describe the structure of solids, liquids and gases in terms of
particle separation, arrangement and motion.
•Describe changes of state in terms of melting, boiling,
evaporating, freezing and condensing

2. Kinetic Theory of Matter
Matter is made up of particles
which are in continual random
motion.

5. Changing State of Matter

6. Applying The Kinetic Particle Theory to
Changes in State

7. Changing State of Matter

8. Melting & Boiling Point
Boiling point (b.p) is a temperature at which a
substance turns into a gas.
When a liquid change into a gas and left with
its surface exposed to the air is called
Evaporation
Melting point (m.p) is a
temperature at which a substance
turns into a liquid. The process in
reverse is called freezing

9. Simulation

10. Lesson 2:
Learning Objectives:
•Describe the effects of temperature and pressure on the volume of a gas.
•Explain, in terms of kinetic particle theory, the effects of temperature and
pressure on the volume of a gas.
•Explain changes of state in terms of kinetic particle theory, including the
interpretation ofheating and cooling curves

11. Key words:
•Temperature
•Energy
•Particle movement
•Intermolecular forces
•Particle distance

12. Use kinetic particle theory to
explain:
The effect of
temperature on the
volume of a gas
• The effect of
pressure on the
volume of a gas

13. Pure Substances
A Pure substance consist of only one substance without any contaminating impurities.
A Pure substance melts and boils at definite temperature. The m.p & b.p can be used to test the purity of a
sample.
Which two substances are liquids at room temperature?

14. Latent heat is the heat needed to cause a phase change to
a specific amount of matter at a fixed temperature. It is
the amount of heat that is absorbed or released divided
by the amount of substance that is undergoing a phase
What happens to the temperature of a substance as it changes state? Constant

17. Lesson 3:
Learning Objectives:
•Describe and explain diffusion in terms of kinetic particle theory.
•Describe and explain the effect of relative molecular mass on the rate of
diffusion of gases
