[S4] Lesson 28 (Thermal Year End Revision + Graph Sketching + Redox & Metals EOY )

[S4 Physics PMCians] 


What we did in 2 hours:

On the 11th and 12th Jul, the S4PH has come together to cover the following during our weekly lesson: 

1) Recap on the concept 1 and 2 of the Thermal Physics I (Temperature and Thermal Properties of Matter)

2) The Final Lap I – MCQ Qn 1 to 14

3) Kahoot Quiz


Always remember: 

1) Thermometric Property is a physical property of a substance that vary continuously with temperature. It is ONLY because of calibration using two fixed points, we THEN assume this relationship is linear. 

2) The approach to solve temperature questions using either the graph method (for R and L) and E = k (HJ -CJ) for Thermocouple. 

3) There are three different formula for thermal energy, namely: Q = m c (change in T), Q = m l, and Q = P x t

4) If you are given two different bodies interacting together through heat transfer, do make a point to list out all the possible Q before solving the questions. 


What you take home:

We will start on Thermal Physics Lesson 2 where we will continue with Thermometry and Thermal Properties of Matter (i.e.: Heat Capacity and Latent Heat) through our usual thinking-aloud approach tackling the structured questions. 

Special Mention:

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

If you have any upcoming test or examination and would want to re-watch any of the past videos, do whats-app to 9100 1235 to inquire!!

Take care and Always with you,

What we did in 2 hours:

We started on Graph Sketching Revision this week. Without computing the large numbers of points required for a detailed plot, we can sketch the graph of a given equation by finding their main features.

We learned that it is essential to determine the x and y intercepts of the curve even though there may be no solution at some time. Next, we moved on discussed on how the symmetry of the curve, domains and asymptotes give important clues as to the shape of a curve. We all can quickly sketch out any graph after the tutorial. Thumb up!


What you take home:

Solutions to 20min Graph Sketching Test, The Last Lap – Take Away Questions and Question 9 are found below:


 Special Mention:

Next week, we will be starting Trigonometry Revision. Please remember to collect PMC Secret Enclosed Booklet 2 beforehand. Take care and see you soon!

What we did in 2 hours:

We have completed our revision on redox and acquired quick tips to calculate oxidation state and identify reduction and oxidation processes quickly and accurately (i.e. remember your priority list and business rules!) 


What you take home:

You are now able to complete the entire Take Home Package on Redox. Do attempt the questions as part of your revision and clarify your doubts in our upcoming lesson.

Special Mention:

We will be embarking metals, the reactivity series and displacement reactions. Here’s a quick video on the displacement reaction of copper using iron: https://www.youtube.com/watch?v=UI2Bb69u7Z4
