An insulated container is used to hold 42.7 g of water at 20.5 Celsius. A sample of copper weighing 9.60 g is placed in a dry test tube and heated for 30 minutes in a boiling water bath at 100.0 Celsius. The heated test tube is carefully removed from the water bath with laboratory tongs and inclined so that the copper slides into the water in the insulated container. Given that the specific heat of solid copper is 0.385 J/(g.Celsius), calculate the maximum temperature of the water in the insulated container after the copper metal is added.
