O Level – Chemistry

O-Level Singapore/O-Level Chemistry Tuition/Chemistry Tutor

Our dedicated and experienced tutors conduct the secondary 3 and 4 classes for both Physics, Chemistry and Biology. Each lesson often begins with a 10 minutes recap session on the previous week’s work as rehearsal allows knowledge to be committed into the long-term memory store. Meta-learning skills such as Robinson’s (1970) SQ3R method (survey, question, read, recite and review) are taught to students for more effective reading of their textbooks.

In general, classes are conducted in a lecture-tutorial fashion. Lectures provide a macro view on the topic and explain concepts and definitions by integrating real-life examples. On the other hand, tutorials are conducted on a question-centric basis whereby students will be taught how to apply these concepts and answer exam questions in a succinct manner. 


Useful concise notes and with exam questions as examples

are available on the following topics.

Chapter 1 – Kinetic Particle Theory

1. Explain why a solid have a fixed shape and volume using kinetic particle theory.

The particles of a solid are held together by very strong forces of attraction. They cannot move freely, and have only enough kinetic energy to vibrate and rotate about their fixed position.

2.  Explain why a liquid does not have a fixed shape using kinetic particle theory.

The particles of a liquid are held together by weaker forces of attraction as compare with solid. They are arranged in a disorderly manner and can move freely by sliding over one another. Thus liquild does not have a fixed shape and take the shape of the container.

3.  Explain why during the melting process, the temperature of the substance does not rise even though heating continue.

The temperature remains constant because all the heat energy taken in by the particles is used to overcome the forces of attraction holding the particles. A mixture of solid and liquid phases exist here.
