Asked by Gunner
How much heat is needed to transform a 2.5kg block of ice at -4C to a puddle of water at 12C.
c water = 4200 J kg C
c ice = 2100 J kg C
Lf = 3.33x10^5 J kg
c water = 4200 J kg C
c ice = 2100 J kg C
Lf = 3.33x10^5 J kg

heat=heatTOice+heattomelt+heatwater
= 2.5kg*cice*(0+4)+2.5*Lf+2.5*cwater*(12-0)
= 2.5kg*cice*(0+4)+2.5*Lf+2.5*cwater*(12-0)
