... (6) therefore states that the internal energy of a system expanded at constant temperature will change, and this change is due to attractive interactions between molecules. Since the ideal gas equation of state neglects these interactions, it predicts no change in the internal energy upon expansion ...

... ‘Thermal mass’ describes materials which have the ability to absorb and store heat. Generally, the heavier and denser the material, the more heat they will store, and the longer it will take to release that heat. To take as full advantage of the sun’s energy as possible, buildings need to be constru ...
