## Homework Statement

In each case, the following are mixed in a perfect calorimeter with no heat lost or gained from the system. Find the final temp in each case.

12.5 g of steam at 100C with 344 g of water at 22.2C.

## Homework Equations

Q=Mc(Tfinal-Tinitial)

M is the mass in kg

C is the specific heat given by whatever substance we are dealing with

And the parantheses is the change in temperature

## The Attempt at a Solution

So I didn't really know where to start with this problem I realize that one of the substances is going to undergo a phase change but am unsure how to find which one does it. If I could help with that I believe I could calculate the final temperature.
