The heat capacities are from Liley et al. (1997). The densities are calculated from the formulations of thermal linear expansion by Touloukian et al. (1975, 1977). Those at temperatures higher than 273 K are calculated from the formulations compiled by Liley et al. (1997). The uncertainties of these formulations are about 2% for most elements listed.
