Explain the final temperature when both metals are placed in the water at 20 degree Celsius? A piece of gold weighing 10.0g(c=0.129 J/g-K) is heated to100.0 degrees Celsius. A piece of copper also weighing the10.0g(c=0.385 J/g-K) is chilled in an ice bath to 0 degrees Celsius. Both pieces of metal are placed in a beaker which is having the 150g of water at 20 degrees Celsius.
