## Homework Statement

Describe the composition and temperature of the equilibrium mixture after 1.0 kg of ice at -40*C is added to 1.0 kg of water at 5.0*C.

## Homework Equations

[tex]

\begin{gathered}

Q = mc\Delta T \hfill \\

Q = mL \hfill \\

\end{gathered}

**Book answer:1.2kg ice, 0.80 kg water, all at 0*C**

## The Attempt at a Solution

I'm not quite sure how to set this one up. I've tried:

[tex]

m_i c_i \Delta T_i + m_w c_w \Delta T_w = 0

[/tex]

With this I found the equilibrium temperature to be -9.8*C...
