The specific heat of most solids is nearly constant over a wide temperature range. Not so for diamond. Between 200 K and 600 K, the specific heat of diamond is reasonably well described by c=2.8T−350J/kg⋅K, where T is in K. For gemstone diamonds, 1 carat = 200 mg.
How much heat energy is needed to raise the temperature of a 2.5 carat diamond from -50∘C to 250 ∘C?
