BENZEN (C6H6)
Melting Point: 5.5C
Boiling Point: 80C
Hf: 127J/g
Hv: 551 J/g
Sample Size: 100g
Sp. Heat (solid): 1.5 J/gC
Sp. Heat (liquid): 17 J/gC
Sp. Heat (gas): 1.0 J/gC
Rate of heating: 400 J/min
How much heat is required to melt the sample at the melting point?
How much heat is required to boil the sample at the boiling point?
How much heat is required to raise the temperature of the sample from 20°C below melting point to the melting point?
What is the difference in temperature between melting point and boiling point?
How much heat is required to raise the temperature of the sample of the liquid phase from the end of melting to the beginning of boiling?
How much heat is required to raise the temperature of the sample of the gas phase from the end of boiling to 20°C above the boiling point?
I need equations, you don't have to do the work!

Let benzene be called B.
100gB x 127J/1gB =
100gB x 551J/1gB =
100gB x 20degC x 1.5J/gB-degC =
80C - 5.5C = 74.5C
100gB x 74.5degC x 17J/gB-degC =
100gB x 20degC x 1.0J/gB-degC =
