1.	Two identical fully insulated flasks X and Y contain the following Flask X (10 g of ice at 0^(@)C + 500 mL of water at 0^(@)C) Flask Y (10 g of ice at 0^(@)C + 500 mL of brine at 0^(@)C) After one hour,
Answer» There is no change in the nature of contents of the two flasks There is no ice in flask X but contents of flask Y remain unchanged There is no change in the contents of flask X but there is no ice in flask Y No ice is there in both the flasks X and Y Solution :Due to equilibrium in flask X the amount of ice will not change with time. As non-volatile IMPURITIES lower the freezing point, freezing point of BRINE is less than `0^(@)C`. Thus, ice in flask Y will melt and temperature of brine will fall below zero.
