Last Sunday, i met the new group of students for the 2010 Sun Sec 3 Chemistry Class under Ultimate Leap Programme.
Since it was the 1st session, i decided to start with a very basic topic known as Particulate Nature of Matter, otherwise known as Kinetic Particle Theory to many. This should be something that most students would have learned and mastered in Sec 1/2 in their secondary schools.
To my surprise, many of the students were not conversant in this topic when i gave them the Pre-Test!
Today, i am going to share with you the overview checklist on what you need to know about this topic as well as discuss on one very important concept that are frequently tested in GCE ‘O’ Levels / IGCSE / IB / IP Chemistry Exams.
Overview Checklist on what you need to know:
- Recognise & draw the particulate models for Solids, Liquids & Gases
- Describe the arrangement & movement of the particles in the 3 States of Matter
- Explain why Gases can be compressed, but not Solids & Liquids
- Describe what happens to the particles during melting, boiling, condensation and freezing
- Interpret Temp / Time Graphs for Changes of States
- State the connection between relative molecular mass of a gas & its rate of diffusion
- State some examples of diffusion of gases in everyday life
Of the above, the favourite question that examiners like to ask is [Read more…] about O Level Chemistry: Particulate Nature of Matter (Kinetic Particle Theory) Part 1
