A 40-g block of ice is cooled to -71°C and is then added to 610 g of water in an 80-g copper calorimeter at a temperature of 23°C. Determine the final temperature of the system consisting of the ice, water, and calorimeter. (If not all the ice melts, determine how much ice is left.) Remember that the ice must first warm to 0°C, melt, and then continue warming as water. (The specific heat of ice is 0.500 cal/g·°C = 2,090...

A block of copper of unknown mass has an initial temperature of 62.4 ∘C. The copper is immersed in a beaker containing 92.1 g of water at 22.6 ∘C. When the two substances reach thermal equilibrium, the final temperature is 25.0 ∘C. What is the mass of the copper block? Assume that Cs,H2O=4.18J/(g⋅∘C) and Cs,Cu=0.385J/(g⋅∘C). Express the mass to two significant figures and include the appropriate units.
