the density of water at 0C is 0.9999g/mL, and the density of ice at 0C is 0.9168g/ml. a) Based upon these densities, does water contract or expand when it freezes? Explain. b) Suppose you have a 250-mL container completely filled with ice (no air bubbles). What volume of liquid water will form when the ice melts? c) In (b),would wter spill out of the container once the ice melted? if so, how much water would spill out? if not, how much water could you add to the container after he ice melted?
