An insulated container is used to hold 48.20 g of water at 17.70 degrees celcius. A sample of copper weighing 16.80 g is placed in a dry test tube and heated for 30 minutes in a boiling water bath at 110.0 degrees celcius. Given that the specific heat of solid copper 0.385 J/g degrees celcius, calculate the maximum temperature of the water in the insulated container after the copper metal is added
