A piece of copper of mass 20.0g at 100oC is placed in a vessel of negliglible heat capacity but containing 50.7 g of water at 22oC. Calculate the final temperature of the water.
The answer is 25oC but i dont know how you get this. The question pertains to a section on heat capacity. The heat capcities of water and copper are 4.184 and 0.38 J/gK respectively
I would presume heat would be exchanged until the copper and the water had the same temperature but i wouldn't know how to calculate when exactly this happened except by trial and error
