The properties listed here (except the vapor density) can be used at any pressures with negligible error except at temperatures near the critical-point value. Note 2: The unit kJ/kg· C for specific heat is equivalent to kJ/kg·K, and the unit W/m· C for thermal conductivity is equivalent to W/m·K.
Table 3 shows the specific heat capacity of solids as a function of temperature, the specific heat capacity of liquids at the melt-ing point (Tm), and the enthalpy of fusion for most common elements found in cast metals.
27 sty 2006 · The purpose of this lab experiment is to measure the specific heat capacity of unknown metal samples and also to determine the latent heat of fusion of water. In addition, we will study the effectiveness of different calorimeters.
1.9859 Btu/lbmol·R. 10.732 psia·ft3/lbmol·R is the universal gas constant and M is the molar mass. Source: Specific heat values are mostly obtained from the property routines prepared by The National Institute of Standards and Technology (NIST), Gaithersburg, MD. TABLE A–2E.
