Please help me solve this problem. I have the answer from the book, but I don't know how to get the answer.
Suppose that 0.48 g of water at 25 degree celsius condenses on the surface of a 55-g block of aluminum that is initally at 25 degree celsius. If the heat released during condensation goes only toward heating the metal, what is the final temperature (in degree celcius) of the metal block? (The specific heat capacity of aluminum is 0.903 J/g times degree celsius)
