Draw what the heating curve would look like for a sample of liquid water at 35degC heated to steam at 120degC. Label your starting temperature, ending temperature, boiling point and the states of matter along the line of the curve. Use the graph to calculate the total energy required to raise the temperature of 225g of water from 35degC to 120degC. (Hint: Only 3 calculations are required.) deltaHvap = +40.7 kJ/mol. c(water) = 4.18 J/g deg. c(steam) = 2.02 J/g degC

Draw what the heating curve would look like for a sample of liquid water at 35degC heated to steam at 120degC. Label your starting temperature, ending temperature, boiling point and the states of matter along the line of the curve.

Use the graph to calculate the total energy required to raise the temperature of 225g of water from 35degC to 120degC.

(Hint: Only 3 calculations are required.)

deltaHvap = +40.7 kJ/mol. c(water) = 4.18 J/g deg. c(steam) = 2.02 J/g degC *
