Specific heat of single-, poly- and nanocrystalline diamond

WebDiamonds are discovered at a depth of around 150-200 kilometers below the surface. And the temperatures range from 900 to 1,300 degrees Celsius, with pressure ranging from 45 to 60 kilobars (about 50,000 times that of air pressure at the Earth’s surface). WebThe heat capacity of solids as predicted by the empirical Dulong–Petit law was required by classical mechanics, the specific heat of solids should be independent of temperature. But experiments at low temperatures showed that the heat … WebThe specific heat of diamond at 500° is about 0.4 cal./g. °C. and this decreases to only 0.0025 cal./g. °C. at 90° K. The average specific heat over this temperature range is about 0.23 cal./g. °C. and the sensible heat is, therefore, 160 cal. per gram. This is about 105 times greater than the heat of adsorption.

WebFeb 1, 1998 · The fact that the specific heat data of the CVD diamond samples fall within a 15% interval around the reference data up to 300 implies that the temperature depen- dence of the thermal expansion coefficient should be the same as that of single-crystalline diamond, if the Grtineisen relation is assumed to hold. WebSpecific heat, or specific heat capacity, is a property related to internal energy that is very important in thermodynamics. The intensive properties cv and cp are defined for pure, simple compressible substances as partial derivatives of the internal energy u (T, v) and enthalpy h (T, p), respectively:
