Q 1 :    

Ice and water are placed in a closed container at a pressure of 1 atm and temperature 273.15 K.                     [2025]

If pressure of the system is increased 2 times, keeping temperature constant then identify correct observation from following:

  • Liquid phase disappears completely.

     

  • The amount of ice decreases.

     

  • The solid phase (ice) disappears completely.

     

  • Volume of system increases.

     

(3)

Increasing pressure compresses the system and takes it towards more dense phase. As water has more density than ice, increasing pressure converts ice to water.
