Figure 3: Heat capacity of molecular liquids.

Experimental and calculated cV (kB=1) for molecular non-rigid supercritical fluids (a, b). Experimental cv and η are taken from the NIST database. Values of α used in the calculation are 6.5 × 10−3 K−1 (CO) and 8.5 × 10−3 K−1 (N2). The uncertainty of both experimental heat capacities and viscosities is about 2–5%. Insets show viscosity fits.
