A drop of water with a mass of 0.48 g is vaporized at 100 ∘C and 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 Celsius of the metal block? (The specific heat capacity of aluminum is 0.903 J/(g⋅∘C).)

Express the temperature in Celsius to two significant figures.

Calculate the amount of heat required to vaporize 84.8 g of water at its boiling point.

Express the heat in kilojoules to three significant figures.

How much heat is required to vaporize 33.8 g of water at 100 ∘C?
