1. The problem statement, all variables and given/known data

A 500.0-g iron bar at 212 C is placed in 2.0 L of water at 24.0 C. What will be the change in temperature of the water ( Assume no heat is lost to the surroundings.)

2. Relevant equations

(Mass of substance)(Specific Heat of substance)( Change in Temp)

3. The attempt at a solution

I am having alot of trouble with this problem. I don't fully understand how I use that forumula to find the change? I know the answer is 5 C. But I don't understand how. I was wondering if someone could explain how you come about to get this answer using the formulas cause this would be very helpful? Do I have to convert anything or what? So confused.
