What are the different types of JC Chemistry tuition classes available at your centre?

We have 3 modes of learning for students to choose from: weekly physical classes at Bishan; weekly online lessons via Zoom; and on-demand video lessons.

Are you the only Chemistry tutor conducting the classes or do you engage other tutors to do that?

Please be rest assured that I conduct all my classes personally and I do not engage other tutors to teach at my centre.

What is your class size at Bishan?

Usually the class size is around 10 to 12 students. Max class size is 16 pax.

Is there makeup lesson if I miss a class?

Yes makeup lesson is available in the same week subject to availability. If makeup class is not possible, the student can view the recorded video lessons at Google Classroom.

Do you have trial lesson available? How much is it?

Yes we do. Fees for trial lesson are for Bishan class and for Zoom online class.

Does your centre offer O Level chemistry tuition? Do you teach IB / IP chemistry tuition? How about H1 Chemistry?

Chemistry Guru specialises in H2 Chemistry for JC1 and JC2 or IP Year 5 and IP Year 6 students only. Find out all the information about A Level H2 Chemistry and the detailed comparison between H1 and H2 Chemistry. We do not conduct lessons for H1 Chemistry, O Level Chemistry, IB Chemistry or IP Chemistry at IP Year 3 and IP Year 4.

A Level Chemistry 2017 Paper 1 Question 5 Solution

In this video we want to discuss 2017 A Level H2 Chemistry Paper 1 Question 5.

Let Chemistry Guru, Singapore's top JC Chemistry tuition centre, guide you through the question.

2017 A Level H2 Chemistry Paper 1 Qn5 Question

Topic tested is on Gaseous State.

For this question we want to use the Ideal Gas Equation to explain why a gas will liquefy under high pressure.

The most important formula in Gasesous State is the Ideal Gas Equation PV = nRT where:

P is pressure in Pa,
V is volume in m³,
n is moles of gas,
R is gas constant 8.31 J K^-1 mol^-1, and
T is temperature in K.

Using this equation we can predict changes in state of a gas when another state changes.

For example:

1. At constant temperature, pressure will increase when volume decrease (Boyle's Law)
2. At constant pressure, volume will increase when temperature increase (Charles' Law).

Option A

2017 A Level H2 Chemistry Paper 1 Qn5 option A

When pressure increase the temperature should also increase based on the Ideal Gas Equation so option A is not true.

Option B

2017 A Level H2 Chemistry Paper 1 Qn5 option B

When pressure increase, temperature increases which means the kinetic energy of molecules should also increase since KE is directly related to temperature.

Therefore option B is not true.
