The First Law of Thermodynamics: Internal Energy, Heat, and Work
In chemistry we talked about the first law of thermodynamics as being the law of conservation of energy, and that's one way of looking at it, but physicists like doing math more than chemists do, so let's talk about the first law in...

U-Values and Specific Heat Capacity _ GCSE Physics
U-values measure how effective a material is an insulator. The lower the U-value, the better the material is as a heat insulator. For example, a cavity wall has a u-value of 1.6, so most of the heat inside the house will stay in the...
