No because solids can't transmit heat by convection, and convection only works because of hotter and quicker moving molecules have a lower density so they rise to the surface. But in a solid, the molecules can't move relative to each other. They only vibrate :)
q = 10p because all of them are multiplied by ten
D = -28 / 4N+25
Hope this helps.
