Calculate the amount of heat (in kilojoules) required to vaporize 2.58 kg of water at its boiling point. Express the heat in kilojoules to three sianificant fiaures. 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 aluminum,...

Part A To determine whether a shiny gold-colored rock is actually gold, a chemistry student decides to measure its heat capacity. She first weighs the rock and finds it has a mass of 4.9 g. She then finds that upon absorption of 54.6 J of heat, the temperature of the rock rises from 25 °C to 58 C. Find the specific heat capacity of the substance composing the rock. Express the specific heat in joules per gram-Celsius to two significant...
