TRANSCRIPT

  • 1. Principles of Chemistry
    States of matter by Angella Genus

2. At the end of this lesson students should be :
Able to demonstrate an awareness that matter is made up of particles
Aware of the different forces of attraction that exist between particles.
General Objectives
3. Specific Objectives
At the end of this lesson students should be able to accurately:
Define the term matter after discussion in class.
statetwo evidence in support of the particulate nature of matter after discussion in class and practical work involving processes, such as diffusion and osmosis
Explain at least five differences between the three states of matter in terms of energy and arrangement of particles(considering freezing, melting, boiling, sublimation and condensation) after discussion in class.
4. Matter
Is
Anything that has mass and occupies space
And has three states
Liquid
Solid
Gas
5. Comparison of the three states of matter
6. 7. Interconversions between the states of matter
8. Interconversions between the three states of matter
9. Osmosisis the movement of particles from a hypotonic solution to a hypertonic solution through a selectively permeable membrane
10. Diffusionisthe movement of particles from a region of high concentration to a region of low concentration until the particles are evenly distributed.
11. Revision Questions
What is matter?
List the three states of matter?
State the interconversions between the states of matter.
Compare the three states of matter based on arrangement of their particles and interparticle forces.
What is diffusion? Give one example.
What is osmosis? Give one example.
