Joe Elliot has two passions in life – guitars, and more importantly, metals. In fact, he has an extensive collection of many different types of metal. His favorites are a bar of aluminium he found in a thrift store in London, and a block of copper given to him by a geology professor. One day, his mischievous son takes the aluminum bar and places it out in the hot Sun, then takes the copper block and puts it in the freezer. When Joe realizes what has been done, he places the two metals in thermal contact with each other within a thermally isolated container. Given that the specific heat capacity of aluminum is about 2.4x that of copper, which metal will undergo the greatest temperature change during the time it takes them to reach thermal equilibirum?
