# [J1] Lesson 28 (Thermodynamics+ Series Expansion +Alkanes)

[J1 Physics PMCians] First Law of Thermodynamics!

What we did in 2 hours:

We moved from a review of what we did in the first lesson, on temperature scales to the Ideal Gas equation, and concluded with the First Law of Thermodynamics. Combining all our understanding from earlier concepts, we practised the problem solving techniques needed to ace this topic.

Special Mention:

We begin our next lesson on a new topic – Simple Harmonic Motion, otherwise called Oscillations!

Till we meet again, have a blessed week ahead.

From you friendly tutors,

Mr Sim & Mr Kwok 🙂

What we did in 2 hours:

Continuing on with Series Expansion, we consolidated all the techniques from the previous week and applied them onto integrated and application questions. These include Maclaurin and Binomial Series as well as the Standard Series and Small Angle Approximations.

Let’s note that while the techniques are essential, it is also critically important to recognise when the question requires a series expansion – using terms such as approximate or estimate, or showing a required result as a polynomial. Additionally, be ready to apply different series expansions in the same question, especially with the polynomial denominators (power -1).

What you take home:

The Daily Dose & worked solutions are linked here, as well as the quiz solutions.

This week we start on Integration Techniques, be mentally prepared!

See You and Stay Healthy!

[J1 Chemistry PMCians] Welcome to Organic Chemistry!

What we did in 2 hours:

We have completed the chapter on Introduction to Organic Chemistry. Do not underestimate this chapter by its name – concepts such as hybridisation and isomerism are not entirely straightforward, as seen in class. After this lesson, I am sure you now have a better appreciation of the various types of isomerism, including cis-trans and enantiomerism.

What you take home:

The solutions to Q23 (Pg26) of the booklet and the summary is found here:

Special Mention:

Next lesson, let us look at alkanes, our first functional group of interest.

See you next week!
