Estimate Melting Point of Lead at 100 atm

[bon]

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 am not sure what formula/principle I am meant to use to work this out.

I've worked out the energy expended per m^3 at 1atm to be 8820 kJ/m^3... what do i do now :S Thanks

anyone able to help please?

Im guessing the clausius-clapeyron equation comes into it but am confused :S surely someone knows how to solve such problems>?

 

[bon]

Anyoneeeee? surely there must be some Physics PhDs on here?
