A piece of copper also weighing10.0g(c=0.385 J/g-K) is chilled in an ice bath to 0 degrees Celsius. A piece of gold weighing 10.0g(c=0.129 J/g-K) is heated to100.0 degrees Celsius. Both pieces of metal are placed in a beaker containing150g of water at 20 degrees Celsius. Calculate the final temperature when both metals are placed in water at 20 degree Celsius?
