Question

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 2 times, keeping temperature constant, then identify correct observation from following:
(1) Volume of system increases.
(2) Liquid phase disappears completely.
(3) The amount of ice decreases.
(4) The solid phase (ice) disappears completely.

Accepted Answer

(4). Increasing the pressure while keeping the temperature constant will favor the liquid phase over the solid phase in a system containing ice and water. At 273.15 K, the solid phase (ice) will disappear completely as the pressure increases, leading to a complete transition to the liquid phase.
