Homework Answers
Let the final temperature be T.
Heat gained by ice = Heat gained by ice at 0o C to become water at 00C + Heat gained by water to temperature T
= 
where ci = sp. heat of water and L = latent heat of fusion of ice
=
Heat lost by juice = 
where cj = sp. heat of juice = 3.77 kJ/kg0C
Now for equilibrium:
Heat gained by ice = Heat lost by juice
=
