Plenary This PowerPoint file contains the Plenary for this chapter in Physics For You. Most of these slides are paired with a corresponding slide in the PowerPoint of the Learning Objectives for this chapter. Only a limited amount of colour has been used on these slides, but of course you can customise them in any way you wish. As well as using the relevant slide to test your students and to evaluate how well they have understood each section of work, you may also find the slides useful for a quick revision course. Chapter 6 - Thermometers Chapter 6 : Thermometers 1. Explain why mercury and alcohol are good liquids to use in thermometers. 2. What is the Kelvin scale? 3. How do we measure the surface temperature of a distant star? This is an opportunity to research a really good answer! Answers Chapter 6 : Thermometers 1. Explain why mercury and alcohol are good liquids to use in thermometers. They expand evenly when their temperature rises 2. What is the Kelvin scale? A temperature scale based on the kinetic energy of molecules 3. How do we measure the surface temperature of a distant star? This is an opportunity to research a really good answer!
