The Kelvin Scale
In Episode 4, The Kelvin Scale, we look at the temperature scale that in many ways is superior to the Celsius and Fahrenheit scales. Zero on the Kelvin scale is equal to -273ºC. And why is -273ºC so special? Because that’s the coldest temperature you can get!
-
Heat Transfer
In Episode 5, Heat Transfer, we look at the three ways that heat energy can transfer from one thing to another: conduction; convection; and radiation. A heat source is useless if heat energy can’t transfer from the heat source to whatever you want heated. Understanding heat transfer is essential if you want to cook good food and if you want to stay warm when it’s cold and stay cool when it’s hot.

Temperature
In Episode 1, Temperature, we get down to the atomic level to explain how hot things are different to cold things, we describe what a temperature scale actually tells us, and demonstrate how we measure the amount of heat energy that water absorbs when it’s heated.
-
Changes of State
In Episode 2, Changes of State, we look at the differences between solids, liquids, and gases, and at why things change state when they absorb or lose heat energy. We also look at the strange example of carbon dioxide, which doesn’t follow the same rules that that most other substances do!
-
Thermal Expansion
In Episode 3, Thermal Expansion, we look at the fact that substances expand when they get hot and contract when they get cold and we explain why they do. We look at how thermal expansion can be a real nuisance, but also how we can put thermal expansion to good use for the good of the world!
