Abstract
Using a precision adiabatic calorimeter, the heat capacity of a sample of 62.5-wt % ethylene glycol-water solution was accurately measured from −188° to 25°C. It was found that the solution readily supercools with a glass transition temperature of −131°C. The change in heat capacity at the glass transition temperature agrees with the theoretical value based on the hole theory of liquids. The change in heat capacity computed from these data was found to be 0.223 cal deg−1·g−1 or 3.69 cal deg−1·``mole of beads''−1.
