Graphite thermal expansion

WebThe thermal expansion of graphite : I. Experimental 479 who was the first to measure the thermal expansion of graphite in the course of his classical researches, was also responsible for the best value of Or. Employing an optical method, he attempted to measure 0'1 by taking care to orient the crystals in the specimen. WebBy definition, Thermal Expansion is the tendency of matter (in our case graphite), to change in volume in response to change in temperature, trough heat transfer. The Coefficient of Thermal Expansion is the value that allows us to calculate the amount of volume change that will occur, with the change in temperature over a specific range.
