Part B Suppose that 0.48 g of water at 25° C condenses on the surface of a 55-g block of aluminum that is initially at 25°C. If the heat released during condensation goes only toward heating the metal, what is the final temperature (in degrees Celsius) of the metal block? (The specific heat capacity of aluminum, Cs,A1, is 0.903 J/(g. °C).) Express your answer in degrees Celsius to two significant figures. IVO ΑΣφ ? T = 22 C Submit Previous...
