## Homework Statement

A 300 cm3 glass is filled with 120 g of ice at 0°C and 210 g of water at 25°C.

(a) Characterize the content of the glass after equilibrium has been reached. Neglect heat transfer to and from the environment.

Find:

mass of water?

mass of ice?

equilibrium temperature?

## Homework Equations

Q=mL

delta Q1 + delta Q2 + delta Q3 = 0

delta q= 0 (for the system)

## The Attempt at a Solution

I don't know how to solve for the latent heat of fusion, so I tried to set up a series of equations from which I would be able to substitute to solve for the unknowns. I ended up with too many variables and not able to isolate them to solve for values. Since the latent heat of fusion is the heat flow necessary to bring about a phase change, I assumed that Q=mL would be a necessary equation, but I can't figure out how to implement the equation to get values. Any help on starting this problem would be appreciated!

Thank-you!
