[S4 Physics PMCians] 


What we did in 2 hours:

On 12 and 13 Sep, the S4 PH has come together to complete the following:

1) Secret Enclosed – Electricity Concept 4, 7 and 8

2) The Final Lap – Electricity MCQ 18 to 22

3) The Final Lap 2 – DC Circuit MCQ 1 to 12 and Structured Qn 17  

Quick Summary

  1. a) Power = VI or I2R or V2/R – this formula is usually used to comment on the brightness of the light bulbs 
  2. b) E = Pt, do remember to that kWh is usually used when you are calculating for cost of electrical energy consumption
  3. c) Safety Features of Fuse, Switch, Earth wire are important key concepts to remember

All solutions to questions 13 to 16 for this week’s Final Lap 2 are made available for you at the shared folder.

Do go over to the folder to download and compare your answers.

What we did in 2 hours:

We have completed our revision on Atmosphere & Pollutants. You are now equipped with essential problem solving processes on interpreting data based questions involving air/fuel ratio and pollutant levels of cars (i.e. low AFR, low air, low oxygen, high levels of incomplete combustion, low temperature of engine, high amounts of CO, low amounts of NOx and vice versa).


What you take home:

You should begin attempting the take home questions on Atmopshere and bring questions to clarify in class, if any!

Special Mention:

We will be kickstarting our revision on ammonia, examining reversible reactions and the Haber Process, as well as attempting some challenging data based questions! See you in class this weekend!
