WebA 115.0-g sample of a metal at 165.0 °C is added to 265.0 g of ethylene glycol (specifix heat = 2.43 J/g･°C) in a calorimeter at 25.8 °C. The temperature of the ethylene glycol rises to 41.5 °C. Calculate the specific heat capacity of the metal, assuming that all the heat lost by the metal is gained by the ethylene glycol. WebEthylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol ... So, while providing freeze protection and an increased boiling point, ethylene glycol lowers the specific heat capacity of water mixtures relative to pure water. A 1:1 mix by mass has a specific heat capacity of about 3140 J/(kg·°C) (0.75 BTU/(lb·°F ...
