Suppose that 0.48 g g of water at 25∘C ∘ C condenses on the surface of a 55-g g block of aluminum that is initially at 25∘C ∘ 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, Al C s , A l , is 0.903 J/(g⋅∘C) J / ( g ⋅ ∘ C ) .)

Astudent pours 10.0 g of salt into a container of water and observes the amount of time it takes for the salt to dissolve. she then repeats the process using the same amounts of salt and water but this time she slowly stirs the mixture while it is dissolving. the student performs the experiment one more time but this time she stirs the mixture rapidly. the dependent variable in this experiment is: time for salt to dissolve speed of stirring amount of water mass of salt
