1st attempt Feedback See Periodic Table See Hint An insulated container is used to hold 48.8 g of water at 17.1°C. A sample of copper weighing 12.1 g is placed in a dry test tube and heated for 30 minutes in a boiling water bath at 100.0°C. 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. C), calculate the maximum temperature of the water in the insulated container after the copper metal is added. 20.3
