How much heat energy is required to convert 45.5 g of solid ethanol at −114.5°C to gasesous ethanol at 145.5°C ? The molar heat of fusion of ethanol is 4.60 kJ/mol , and its molar heat of vaporization is 38.56 kJ/mol . Ethanol has a normal melting point of −114.5°C and a normal boiling point of 78.4°C . The specific heat capacity of liquid ethanol is 2.45J/g⋅°C , and that of gaseous ethanol is 1.43J/g⋅°C .

it would be a gas formation

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
