[S3] Lesson 26 : Kinetic Model + Maths MYE Revision Set B + Redox Part 2 Updates/Debrief

[S3 Physics PMCians]

What we did in 2 hours:

On the 25th, 27th and 28th June, the S3PH has come together to cover the following during our weekly zoom lessons:

1) Kinetic Model of Matter Notes and Summary

2) Kinetic Model of Matter Test

Always remember:

1) Pressure is affected by FOC and speed of molecules

2) Volume is related to average separation distance between molecules

3) Temperature is related to average kinetic energy of the particles

4) To explain any physical properties related to states of matter, always include the Molecular Arrangement and Intermolecular Forces.

Special Mention:

We will start our Thermal Physics journey with the Temperature and Thermal Properties of Matter I

Should you have any questions, please feel free to send in your questions (and attempted workings) to 9100 1235 (PMC HQ). We will do our utmost to assist you in the questions.

Take care and Always with you,

The S3PH Tutors

What we did in 2 hours:

This week, we continued to look at more question types on chapters covered in Semester 1.

To sum up, we covered these chapters

• Logarithm functions
• Exponential functions
• Application of Surds
• Polynomials
• Coordinate Geometry

Please try the booklets as homework before referring to the solutions:

• MYE, Polynomials
• MYE, Partial Fractions

Special Mention:

In the next lesson, we will continue on Trigonometry and its applications. We will learn to interpret and solve problems in 3-dimensional diagrams. Remember to bring your Book 3 if you are joining us onsite! See you in class (or in zoom)!

What we did in 2 hours:

We discovered what it meant to be a reducing and oxidising agent (recall: what is reduced is an oxidising agent and vice versa) and their color changes  (e.g. potassium manganate turns from purple to colorless, indicating that it is acting as an oxidising agent, which also means the reagent that is was reacting with was acting as a reducing agent. They are partners!).

You are now able to complete the entire Take Home Package. Please attempt the questions and prepare for a quick-fire quiz this weekend!

Special Mention:

We will be kickstarting our lesson on the Periodic Table where we learn about trends of elements across the Period and down their Groups. Here’s an infographic:

Stay healthy, stay safe, see you this weekend!
