Web21 de nov. de 2015 · Looking on the NIST fluid properties database I see that the specific heat capacity (i.e. the heat capacity per unit mass) of D2O is just 1.5% higher than the specific heat capacity of H2O. So at 298 K this makes the molar heat capacity of D2O (84.963 J/K/mol) an astonishing 12.7% higher than H2O (75.38 J/K/mol). Web5 de jun. de 2015 · Specific heat at constant pressure represents the heat supplied to a unit mass of the system to raise its temperature through 1K, keeping the pressure constant. Since, P= Constant, dV > 0 and the work done by the system, W = PdV > 0. The first law of thermodynamics says: Q = (dU+W) = (dU+PdV) > dU. In thermodynamics, the specific heat capacity (symbol c) of a substance is the heat capacity of a sample of the substance divided by the mass of the sample, also sometimes referred to as massic heat capacity. Informally, it is the amount of heat that must be added to one unit of mass of the substance in order to cause an increase of one unit in temperature. The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg ⋅K . For example, the heat required to raise the temp… liters of water to m3
