The specific heat capacity of water is 4200Jkg−1K−1 and its densities at 00C and 40C are 999.9kgm−3 and 1000kgm−3 respectively. atmospheric pressure =105 Pa. View Solution Find the change in the internal energy of 2kg of water as it heated from 00C→40C. The specific ...
Specific heat capacity of the nanofluids is generally measured by the differential scanning calorimeter (DSC). In this method, the reference material (generally water) and the sample material temperature rise is measured due to heating and the sample heat capacity is determined. The majority of the...
GÖRAN GRIMVALL, in Thermophysical Properties of Materials, 1999 4 Heat capacity Since we now deal with strictly harmonic vibrations, the heat capacities Cp and CV, taken at constant pressure and constant volume, respectively, are equal (= Char). Thermodynamics gives (7.25)Char=(∂Ehar/∂...
The heat capacity at constant volume CV of pure water has been measured in the temperature range from 412 K to 693 K at 13 isochores between 250 kg·m-3 and 925 kg·m-3. Measurements cover the critical region and coexistence curve. Measurements have been made in both the one- and two...

In the case of liquid tungsten, the literature consensus is also that the enthalpy at constant pressure is a linear function of the temperature. This implies a constant isobaric heat capacity, courtesy of (∂H/∂T)P=Cp. Thus, also the specific isobaric heat capacity cp=∂Cp/∂m ...
