A Slush of Liquid Water and Ice Crystals Is at Equilibrium

Multiple Choice

A slush of liquid water and ice crystals is at equilibrium at 0 ° C. If a small amount of heat is removed so that more ice is formed, the system will experience:

A) a temperature rise since crystallization of ice is an exothermic process.
B) a change in vapor pressure over the mixture.
C) a temperature lowering since more ice produces a colder system.
D) a change in pressure that is proportional to the heat.
E) no temperature change.
