How does melting point of ice change with increase in pressure?

When the pressure on the ice is increased, the ice water system will acquire the equilibrium at the lower point. The volume of ice is less than that of water. Increase in the pressure can lower its volume more. So, the melting point of ice is reduced.

What is Relegation how skating is possible on snow explain?

It is due to regelation that skating is possible on snow due to the formation of water. Water is formed due to the increase of pressure and it serves as a lubricant.

What is relegation explain with an example?

to put someone or something into a lower or less important rank or position: She resigned when she was relegated to a desk job. If a football team is relegated, it is moved down to a lower division: If Southampton lose again they may be relegated from the Premier League to the First Division.

What is the effect of increase in pressure on i the boiling point of a water 2 II the melting point of ice?

(i) Melting point of ice decreases with an increase in the pressure.

How can you increase the melting point of ice?

One way to raise the melting point of water is to increase pressure beyond about 635 MPa. By raising pressure you could get the melting point to be even greater than the normal boiling point. A second way is to lower the pressure, but this can only increase the melting point by 0.01 K.

What is the relegation give its one practical application?

Regelation is a process in which the state of a substance can be changed by application of pressure and then releasing it. A substance (that is frozen solid) can melt when pressure is applied and when lifted it freezes again.

Why is it easy to perform skating on snow?

It is easier to perform skating on snow than on ground. This is because there is less friction in the case of snow. Also, the application of pressure by the skate board, leaves a apparent layer of water on the snow which helps in motion.

What is relegation or refreezing?

The phenomenon in which the ice melts to water at lower temperature due to increase in pressure and refreeze again due to decrease in pressure is called relegation.

What is the sentence of relegated?

(1) Women tended to be relegated to typing and filing jobs. (2) Some people believe that Communism has been relegated/consigned to the scrap heap of history. (3) She resigned when she was relegated to a desk job. (4) He has been relegated to the position of an assistant coach.

Why does boiling temperature of liquid increase with pressure?

The boiling point of a liquid is directly affected by atmospheric pressure. This is the pressure exerted by the weight of the air molecules above the liquid. In an open system this is called atmospheric pressure. The greater the pressure, the more energy required for liquids to boil, and the higher the boiling point.

When pressure applied to a liquid increases the boiling point?

The boiling point increases with increased pressure up to the critical point, where the gas and liquid properties become identical. The boiling point cannot be increased beyond the critical point. Likewise, the boiling point decreases with decreasing pressure until the triple point is reached.
