Web9 de jul. de 2024 · Temperature changes of the plate are governed by the heat equation. The solution of the heat equation subject to these boundary conditions is time dependent. In fact, after a long period of time the plate will reach thermal equilibrium. If the boundary temperature is zero, then the plate temperature decays to zero across the plate. http://home.iitj.ac.in/~k.r.hiremath/teaching/Lecture-notes-PDEs/node26.html country clippers pelham ga
