mc(delta)T=mc(delta)T

One for the water values and one for the copper values

One for the water values and one for the copper values

You are assuming for this problem that the heat (q) lost by the water is equivalent to the heat (q) gained by the calorimeter (in this case the copper pot?) therefore you can use mc(delta)T=mc(delta)T to calculate the heat lost by the water and find the final temperature of the water.
