Temperature Change and Heat Capacity Physics

A 0.250kg block of a pure material is heated from 20.0 186C to 65.0 186C by the addition of 4.35 kJ of energy. Calculate its specific heat and identify the substance of which it is most likely composed. Suppose identical amounts of heat transfer into different masses of

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 ...
