Entropy is seen in situations that involve the dispersal of energy from a concentrated state to a less concentrated one, such as a hot pan cooling down, a tire blowing and releasing its air, the rusting of metal or cream... More »

Some thermodynamics problems include state evaluation of pure science issues, basic challenges, problems involving a closed system undergoing a process and closed steady systems problems. Other problems are those that in... More »

Soluble substances are those that easily dissolve in a solvent, such as water, and include sugar, salt, alcohol and some dishwashing detergents. In chemistry, solubility of a substance is a quantitative term that refers ... More »

A Schauberger generator is a device that is purported to create a positive net gain of energy from water or air flowing through it. This functionality is disputed by many skeptics and physicists. More »
