The specific heat of aluminum metal equals 0.90O JK g¯. Consider a process in which a 25 g piece of aluminum metal, at an initial temperature of 90 °C, is dropped into a 100 g sample of liquid water contained in a thermally insulated Dewar flask at an initial temperature of 20 °C. What would be the final temperature of the aluminum sample after the aluminum-water system has reached a state of thermal equilibrium?
