You are mixing water with ice in an insulated container. The temperature of the ice is initially below its freezing point. The following are given:. the amount of heat absorbed by the ice if heated to its melting point: 400 J,
the amount of heat absorbed by the ice if it all melts (which includes the heat needed to bring the ice to its melting point): 2100 J,
the amount of heat given off by the water if cooled to its freezing point: 2400 J, and
the amount of heat given off by the water if it all freezes (which includes the heat needed to bring the water to its freezing point): 5200 J.
Based on this information, at equilibrium, which phases are present?
