[S4] Lesson 27 (Thermal Year End Revision + Graph Sketching + Redox & Metals EOY )

[S4 Physics PMCians] 

 

What we did in 2 hours:

On the 3rd and 4th Jul, the S4PH has come together to cover the following during our weekly zoom lessons: 

1) Recap on the concept 1 and 2 of the Dynamics in Secret Enclosed

2) The Final Lap II – Structured Questions 1 to 5 

3) 8Q challenge 

Always remember: 

1) A free-body diagram is the first step to solve any forces related questions before you use the F(res) = ma

2) To explain water resistance or air resistance-related motion, a free-body diagram is helpful. And, remembering how drag force is related to speed is essential.

3) For any forces to qualify as Action- Reaction pairs for N3LM, go through the 4 critieras. 

 

What you take home:

We will start on Thermal Physics Lesson 1 where we will begin with Thermometry and Thermal Properties of Matter (i.e.: Heat Capacity and Latent Heat) 

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. 

 

Take care and Always with you,

What we did in 2 hours:

We started on Linear Law Revision this week.  We talked about how to linearize a “complicated” equation into linear equation and hence find the unknown by comparing the gradient and y-intercept. We practised on graph drawing, however some of you took longer than expected to finish the graph. Bear in mind that you should not spent more than 10 minutes on the graph, more practice using our Take Away Questions will help.

 

What you take home:

The Last Lap – Take Away Questions and Qns 3 and Q4 Graph Solution

 Special Mention:

Next week, we will be looking into how to sketch modulus, exponential and logarithm graphs. Take care and see you soon!

What we did in 2 hours:

We have completed our revision on Stoichiometry and acquired efficient tips to visualise complicated back-titration and scenarios that require multiple steps and reactions by drawing. Do apply these techniques in your daily practice if you have found the tip useful! 

 

What you take home:

You are now able to complete the entire Take Home Package on Stoichiometry. Do attempt the questions and have questions answered any time.

Special Mention:

We will be embarking on Redox and Metals. Here’s a quick infographic on Group I metals!
