## Homework Statement

A 1kg of ice at -30° C is added to 10 kg of steam at 500°C. answer the following questions: a) What is the final phase of the system of ice + steam if no heat escaped from it.

b) What is the final temperature when the equilibrium is established

## Homework Equations

Q= mc (delta) T

Q= mL

## The Attempt at a Solution

I am assuming that the final phase will be steam.

I have tried multiple times, but I cannot seem to get the answer. I know that

Q(-30 --> 0) + Q (ice fusion) + Q(0 --> 100) + Q(heat of vaporization) + Q(Tf - 100) = Q(Tf - 500).

Any help would be greatly appreciated
