Thermal Equilibrium Chemistry Video Clutch Prep
When a fresh breath of air is drawn into the lungs, it is heated by your body. Lets assume it reaches thermal equilibrium with your body temperature of 37 176C. Given the temperature, pressure, and the average molar mass of air, you could easily calculate that

Silicon can be made to melt in reverse MIT News Massachusetts
2010/8/2 0183 32For example, when a liquid is heated, it can dissolve more of another material, but then when cooled down it can become supersaturated, until the excess material precipitates out. In this case, where the metals were dissolved into the solid silicon, if you begin cooling it down, you hit a point where you induce precipitation, and it has no choice but to precipitate out in a liquid phase ...
