Specific heat, or specific heat capacity, is a property related to internal energy that is very important in thermodynamics. The intensive properties c v and c p are defined for pure, simple compressible substances as partial derivatives of the internal energy u(T, v) and enthalpy h(T, p) , respectively:
WebWe define the molar heat capacity at constant volume C V as. C V = 1 n Q Δ T, with V held constant. This is often expressed in the form. Q = n C V Δ T. 2.13. If the volume does not change, there is no overall displacement, so no work is done, and the only change in internal energy is due to the heat flow Δ E int = Q. WebGallium is a blue-gray metal which becomes a silvery liquid at 29.8°C. It has the rather startling property of melting in your hand. Like water, it expands on freezing. It's heat of fusion is 8.04 x 10 4 J/kg. Its chemistry resembles that of aluminum.
