This resource contains the theory, examples, questions and answers regarding Newton’s Law of Cooling. You will find a fun and colourful slide show that illustrates this theorem, as well as some interesting examples that will allow students to think critically and arrive at solutions. Here is a typical example: At 06:00 am, a detective finds a murdered body. Temperature of the body is 30 degrees celsius. By 08:00am the temperature dropped to 25 degrees celsius. Surrounding air temperature is 20 degrees celsius. Using the fact that when alive, the human body is 37 degrees celsius…find out when the murder was committed. Students will become real life detectives here. Equipping them with out of the box knowledge. Have fun! Kind Regards ENTER - ONE

Here are some typical questions you will find: QUESTION 6 Acid rain has a pH that is low enough to cause environmental damage. (a) NO2 is an atmospheric pollutant that reacts with rainwater to form acid rain. (i)(1) Write an equation for the reaction of NO2 with rainwater. 2NO2 + H2O → HNO2 + HNO3 (2) Hence, explain why the pH of acid rain is lower than that of rainwater. •ionises completely in water •acid has formed •HNO3 → NO3- + H+ •[H+] increases so pH decreases (ii) Identify another atmospheric pollutant that can contribute to the formation of acid rain. SO2, SO3 NO We hope you use this resource to aid your learning and teaching Kind Regards ENTER - ONE
