Homework Statement
An adiabatically isolated system consists of 1 mol of a diatomic gas 100K and 2 mol of a solid at 200K separated by a rigid adiabatic wall. Find the equilibrium temperature of system after adiabatic wall is removed, assuming that the solid obeys the Dulong-Petit law.
Homework Equations
mgascgas(T-100) = msolidcsolid(200-T)
mgascgas = Qgas = 5/2 nRT ( 5 is degree of freedom, I guess so)
The Attempt at a Solution
5/2 nRT = Q = msolidcsolid(200-T)
4. Answer
171K
