Question

Ice and water are placed in a closed container at a pressure of 1 atm and temperature 273 K. If pressure of the system is increased to 2 atm while keeping temperature constant, which of the following would be the correct observation ?

• A. The liquid phase disappears completely
• B. The amount of ice decreases
• C. The solid phase (ice) disappears completely
• D. Volume of the system increases

Answer 1

Answer: (C)

The solid phase (ice) disappears completely

Answer 2

Ice $\rightleftarrows$water ; due to conversion ice to water volume decreases

Due to increase in pressure, the conversion of ice to water is favoured
