21. How much heat is required to change m=1 kg of ice at -6oC into water at 60oC ? cw=4190 J/KgK(specific heat of water), Lf=333kJ/Kg (latent heat of fusion for ice), cice=200J/kgK (specific heat of ice).
Homework Answers
Q = mcice
T
+ mLf + mcwT
Q = 1*2100*(0-(-60))+1*333*10^3+1*4190*(60 - 0)
Q = 710400 J
