Question

State the effect of increase of pressure on the melting point of ice.

Answer 1

Hint: The molecules of the substance move away from each other when the solid substance is heated. Solid matter is then transformed into a liquid state. The ice is the water's solid form. It gets converted into water when the ice is heated. A substance's melting point is the temperature at which the state changes from solid to liquid. The solid and liquid stage in equilibrium exists at the melting point

Complete solution:
The pressure is the matter's external physical state. When any system's external component changes, it will try to take the system out of equilibrium. LeChatelier's principle describes this phenomenon. The system then adjusts to the changes made to the system.

Thus, according to the LeChatelier principle, the following changes can be observed on the ice: The ice water system will acquire equilibrium at the lower point when the pressure on the ice is increased.
1.Less space can occupy more ice.
2.The ice volume is less than the water volume.
3.Increased pressure can further lower its volume.

So, the ice's melting point is reduced. The melting point of the ice is reduced at lower temperature.

Note:
The melting point is the temperature of the solid substance at which it gets converted into liquid. The melting points are inversely proportional to the pressure. The solid substance is directly converted into a gaseous state, this process is known as sublimation. The melting point of a substance depends on the pressure and is normally specified as 1 atmosphere or 100 kPa at a standard pressure.
