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, c s, al , is 0.903 j/(g⋅ ∘ c) .) express the temperature in degrees celsius to two significant figures.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
