    Ice and water are placed in a closed container at a pressure of 1 atm and temperature 273.15 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

    Correct Answer: C

    Solution :

    \[Icewater\] At P=1 atm and T=273.15K For  \[\operatorname{P}>1\,atm\] and \[T=273.15K\], equilibrium shifts completely in forward direction leading to reduction in volume of the system, i.e., ice melts completely.
