1. What effects can heat transfer have on H2O, if no
chemical reactions occur?
a) At 0°C, the
temperature of the water in an ice-water mix may increase, or the
temperature of the ice in the ice-water mix may decrease.
b) Either the
temperature of the water will change or the phase will change, but
not both at the same time.
c) At 0°C, ice will
expand as it turns into liquid water.
d) None of the
above.

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,...
