CHEMISTRY 101: Thermal Energy Transfer Between Metal and Water

In this example, we solve for the final temperature when a hot metal is added to cold water.

A 15 g block of aluminum metal originally at 98 degrees Celsius is dropped into 55 g of water originally at 25 degrees Celsius. If the specific heat of water and aluminum are 4.18 J/(g C) and 0.903 J/(g C), respectively, calculate the final temperature of the metal and water.
