The human body obtains 1048 kJ from a candy bar. If this energy were used to vaporize water at 100 ∘C, how much water in liters could be vaporized? Assume that the density of water is 1.0 g/mL. The heat of vaporization of water at 100 ∘C is 40.7 kJ/mol. (Hint:Begin by using the enthalpy of vaporization of water to convert between the given number of kilojoules and moles of water.) Express your answer to three significant figures and include...

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,...
