It's called "regelation" and is why ice is slippery to walk on. Solid water is no more slick than any other material, but when walked upon, the downward pressure causes a thin layer of water to liquify at the interface between ice and shoe leather. This liquid layer acts as a lubricant, momentarily reducing the coefficient of friction to nearly zero. Any sudden moves, and down you go!

High pressure under skaters shoes lowers melting point of ice explain?
Under the pressure exerted by skates, the melting point of ice decreases due to the compression of the ice crystals. When pressure is applied, the ice molecules become more tightly packed together, causing a decrease in the amount of energy required for the molecules to transition from a solid to a liquid phase. This is why the pressure from skate blades can lead to the melting of ice beneath them, allowing for smooth gliding.
What is the temperature of ice water before the ice is completely melted?
It depends slightly on the atmospheric pressure. At standard pressure the answer is 0 C or 32 F
Why water at bottom of ice in Atlantic ocean not converted to ice?
The pressure at the bottom of the ocean is very high. Water is unique in that as pressure increases, its melting point decreases. This means that it stays liquid a lower temperatures when it is under high pressure. The presence of salt in the water lowers the melting point even more.
What is the effect of change in pressure in melting point?
Putting a substance under pressure increases its melting point because substances expand as they melt. Putting them under pressure makes it harder for them to expand, which means that they require more energy (heat) in order to transition from a solid state to a liquid state. If a substance is under pressure, decreasing the pressure will lower its melting point.
Does there occur any change in melting point of ice by variation of pressure?
Yes, increase in pressure causes the freezing point to drop.
What will be the melting point ice if it is kept under high pressure?
The melting point is not changed by pressure. It is still over 32O
When pressure on a piece ice is increased its melting point will be?
The melting point of ice actually DECREASES with an INCREASE in pressure.

How does the snowfall change to ice?
Snow primarily changes into ice be melting and refreezing. In glaciers, snow is crushed and recrystallizes under pressure.

It depends slightly on the atmospheric pressure. At standard pressure the answer is 0 C or 32 F
Will melting dry ice make a water puddle?
Unless the dry ice is under pressure, it will "sublime" and change from a solid to a gas. Therefore, there will be no "puddle".

When was Under Pressure - Ice Ice Baby - created?
Under Pressure - Ice Ice Baby - was created in 2011.
What is the name of the line marked 0 degrees Celsius?
It is the melting point of pure ice and the freezing point of pure water under standard pressure.
What is regelation?
Regelation refers to melting under pressure as well as freezing under reduced pressure.
Pressure of a nickel causes ice to do what?
If the ice is right at or close to the melting point temperature at ambient pressure, the pressure of a nickel will cause ice to melt and allow the nickel to penetrate into the ice, displacing the melted water as it goes.
Melting point of ice?
If the ice is free of impurities and the pressure is standard atmospheric pressure, then it melts at zero° C / 32° F / 273.15 K.
