Homework Statement
When lead is melted at atmospheric pressure the melting point is 327.0 degrees C, the density decreases from 1.101 x 10^4 to 1.065 x 10^4 kg/m^3 and the latent heat is 24.5 kJ/kg. Estimate the melting point of lead at a pressure of 100 atm.
Homework Equations
The Attempt at a Solution
Ok So i know how to get the right answer - which i think is 600.754 K as follows:
Clausius-C equation: dp/dT = L/T delta (V)
so i just say that delta p = L/T delta V delta T
Substituting in the values, I get the right answer..
My question is - why is this a valid move? surely it assumes L/T(deltaV) to be constant? Must it be?
