Use the information provided to calculate the quantity of heat (in kJ) required to convert 59.22 g of substance A from an initial temperature of -8.998ºC to a final temperature of 53.2ºC. The molar mass of the substance is 31.20 g/mol. Melting Point of A = 1.110ºC Heat of fusion = 11.32 kJ/mol Boiling point of A = 109.9ºC Heat of vaporization = 86.91 kJ/mol Solid Liquid Gas Specific heat (J/gºC) 2.22 4.1 6.4
What takes more energy: raising water to its boiling point, or making it become water vapor? Why (mention molecular forces)?
a) Water can be sterilized by boiling. How much heat is required to heat 6 gallons of liquid water? (1 gallon=3.78 liters) from room temperature (77°F) to 212°F? b) If the heat of vaporization of water is 40.7 kJ/mol, how much heat would be required to convert the 6 gallons of water now at 212° to steam? Assume the density of water is 1 g/mL at 77°F.
