This is the question...
What is the maximum mass of lead you could melt with 1000 J of heat, starting from 20C?
I know that for lead
Tm = 328 degrees C
Lf (j/k) = 0.25 x 10 ^5
Tb = 1750 degrees C
Lv = 8.58 x 10^5
but I'm not really sure what i need to use. Q = Mc delta T
but how can you figure this without having an ending temperature? I'm confused. Anyone have an idea?
