In a volume dV there are (N/V)dV bonds. So it takes (N/V)dV*E energy to break them

dN? so I need to create a function which relates N to dt? Okay so would that look something like fPt? or do I need to relate it to surface area because it evaporates from the outside in?

Homework Statement Ina light bulb, billions of electrons flow through the tungsten wire bumping around, causing the filament to glow hot. Hot tungsten evaporates slowly, so its initial thickness profile r(x, t=0) can change over time. Consider a volume V of tungsten, with N bonds total, each...
