Skip to 0 minutes and 4 seconds I’m going to start this week with ideas that you are probably already familiar with. Energy can neither be created nor destroyed. It can be transformed into different forms, but it’s always conserved. This is the first law of thermodynamics. I will also explain the zeroth law of thermodynamics, which is about thermal equilibrium and leads to temperature as a measure of thermal energy. We already use temperature to compare the energy of bodies by talking about something being hotter or colder than something else, so we’ll look at what this really means.

Skip to 0 minutes and 40 seconds The week will be wrapped up with a discussion on energy transformations and a lab exercise for you to perform in your kitchen so that you can explore some of the concepts introduced during the week.

Week 1 Introduction

A brief overview of what’s coming this week including conservation of energy and the strangely named, Zeroth Law of the Thermodynamics. A PDF of explanations to symbols that are used throughout the course is available to download at the bottom of the page. You will find this PDF useful in any of the worked examples found in this course. It will also help you to make sense of any mathematical or scientific symbols referred to in the courses content. You may wish to refer to it as a glossary.
