[J2] Lesson 40 (Thermal Physics Grade A Lesson 1 + Grade A Questions – Calculus L3 + Grade A Qns (Ionic Equilibrium) L2)

This week, we completed our Grade A questions series, ending with Thermal Physics.

In this topic, we reviewed the 3 important concepts:

1) Q=mc(DT) and Q=mL

2) Ideal gas equation of states (pV = nRT), and related equations,

3) First law of Thermodynamics, DU = Q + W

Next lesson onwards, we will begin our countdown to the A-level exams, by attempting Mock Papers, specially curated by PMC.

Please be reminded that we will be using the New and final booklet resource from next week.

Till we meet again, be safe and stay healthy!

From you friendly tutors,

Mr Sim & Mr Kwok 🙂

Continuing with our Grade-A Calculus practice, we tackled some interesting questions! We will continue to build up more exposure to different geometry problems, as these are often one of the bigger barriers in differentiation questions, like the similar triangle in the folded paper problem.

Additionally, some classic setting styles that have been in multiple and recent A-level papers: 

1. The reverse factor formula and evaluating periodic sine/cosine values have appeared a few times in recent years
2. F-math in our H2 math! Ask your f-math friends about iterative integration, which is what we did in that question. The 2018 paper included f-math concepts too, but just like what we did, it can definitely be managed by our existing skills, follow the question instructions and do not panic 🙂

Term 4 Quiz L has been updated into the link. Quiz K solutions will be in the folder on Friday.

More Calculus this week, followed by some Sequences & Series.

See You and Stay Healthy!

This lesson, we have completed our revision on Chemical Bonding, looking at the solubility of substances in water and its energy requirements. We have also went through several examples on the drawing of hydrogen bonds.

We moved onto Grade A Questions on Ionic Equilibrium, which includes acid base equilibria and solubility equilibria. These questions not only help push your concepts further, they will also help to reinforce the basic concepts.
