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.
Q = mc\Delta T \hfill \\
Q = mL \hfill \\
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:
m_i c_i \Delta T_i + m_w c_w \Delta T_w = 0
With this I found the equilibrium temperature to be -9.8*C...
