The heating curve for a sample of pure ethanol is provided above. the temperature was recorded as a 50.0 g sample of solid ethanol was heated at a constant rate. which of the following explains why the slope of segment t is greater than the slope of segment r ? a) the specific heat capacity of the gaseous ethanol is greater than the specific heat capacity of liquid ethanol. b) the heat of vaporization of ethanol is less than the heat of fusion of ethanol. c) the specific heat capacity of the gaseous ethanol is less than the specific heat capacity of liquid ethanol. d) the heat of vaporization of ethanol is greater than the heat of fusion of ethanol.
