Finding dp/dt at the boiling point?

Question

The boiling point of ethyl alcohol is 78.3 C,the heat of vaporization is 855 joules/gm.?
find the dp/dt at the boiling point.

Answer 1

I assume you want dp/dT.

Have you tried messing with the 'Thermodynamic Equation of State'

(dE/dV)¦T + P = T*(dP/dT)¦v

where ¦ means evaluated at constant T or v.
AND d means partial differentials

There are loads of these types of equations, and assuming you have all the requisite other Parameters you should be able to find onethat gives you an answer.
