## Homework Statement

An M gram chunk of hot iron is placed on a large piece of 0 ºC ice, causing m grams of ice to melt.

a. What will be the final temperature of the system?

b. What must have been the initial temperature of the hot iron?

c. What must have been the initial temperature of the hot iron?

d. Calculate part c) based on the following information M = 250g, m = 48g and the specific heat of iro in 0.44J / g ºC.

## Homework Equations

q=mC(tf-ti)

## The Attempt at a Solution

how am i ment to know what the final heat is without being given the heat of the iron all i know is it is above 0 ºC unless i am giving the answer as an equation?

am i missing something really obvious?
