<<< Here is some basic physics you need to understand about heat & temperature, which is useful if you want to design things like ovens, heaters, fridges, clothes and houses, etc.
Below in the sub-pages are the kinds of technologies which make use of this science.
Eureka! shows viewers how Swedish scientist Anders Celsius invented the Celsius thermometer, using the expansion of mercury as a measure of temperature.
Eureka! explains that heat refers to quantity of hotness, and is determined by the mass and speed of molecules. This program demonstrates that a bucket of water at a temperature of 50?C contains more heat than a cup of water at 100?C
This program explains how the principle of buoyancy is responsible for the process of heat transfer called convection
Heat is produced whenever there is movement and friction between two objects. Since movement is a form of energy, it follows that heat must also be a form of energy.
Viewers learn that one of the chief ways in which heat energy moves is in the form of waves. This kind of heat transfer is called radiation.
Here you can see the video series Eureka Tutoring
A Rap of Conduction, Convection, and Radiation done for a school project

In the video we try several different types of insulation, including paper towels, newspaper and aluminum foil to see which one keeps the heat in the best.
