Question 12 1 pts How much thermal energy (in 10ⓇJ) is required to boil 2.25 kg of water at 100.0°C into steam at 145.0°C? The latent heat of vaporization of water is 2.26 X 100 J/kg and the specific heat of steam is 2010 J/kg °C. (Answer should have three significant digits. Do not include the exponential part. Example: Fill in the blank ___x 106 J).
Calculate the final equilibrium temperature when 10.0 grams of steam initially at 100 degree C is mixed with 450 grams of liquid water and 110 grams of ice at 0 degree C in a calorimeter. That is, the liquid water AND the ice are initially at 0 degree C. Ignore any heat energy exchanges with the calorimeter and the surroundings. If you conclude that the final temperature of the system is 0 degree C, then what mass of ice remains,...
