How many grams each of the following, per 1000g of water in your car radiation, are needed to give equal protection against freezing down to -10 degrees C? (a) Methyl alcohol, CH3OH (b.p. 65 deg C), (b) ethyl alcohol, C2H5OH (b.p. 78 deg C), (c) ethylene glycol, C2H4(OH)2 (b.p. 197 deg C). In spite of higher costs, what advantage does ethylene glycol have over the alcohols as an all winter antifreeze?
