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 :
On the phase diagram of water, the solid–liquid coexistence line has a negative slope because ice is less dense than liquid water, so raising the pressure at constant temperature favours the denser liquid phase. Starting exactly on the ice–water coexistence line at 273.15 K and 1 atm, doubling the pressure to 2 atm at the same temperature moves the system into the liquid-only region of the phase diagram, so all the ice present converts completely to water.
