As the pressure increases between the skates and ice, the ice starts melting below 0o C.

Skating is possible on snow due to the formation of water below the sk...
**Explanation:**
When we skate on snow, the friction between the skates and the snow causes the ice on the surface of the snow to melt. This melted ice forms a thin layer of water on which the skates glide. This phenomenon is known as "ice skating on snow" or "snow skating." The formation of water below the skates is a result of an increase in pressure between the skates and the snow.
**Increase in Pressure and Melting:**
- When we stand or glide on skates, our body weight exerts pressure on the snow beneath the skates.
- The pressure exerted by the skater's weight causes the snow particles to compress and come into closer contact with each other.
- As a result, the melting point of ice decreases due to this increased pressure.
- The pressure causes the ice to melt and form a thin layer of water between the skates and the snow.
**Role of Pressure in Ice Melting:**
- The melting point of ice decreases as the pressure on it increases. This is known as the pressure-temperature phase diagram of water.
- Under normal atmospheric pressure, ice melts at 0°C. However, when pressure is applied, the melting point decreases.
- The increase in pressure between the skates and the snow causes the melting point of the ice to drop below 0°C.
- As a result, the ice on the surface of the snow melts, forming a layer of water beneath the skates.
**Water as a Lubricant:**
- The thin layer of water acts as a lubricant, reducing the friction between the skates and the snow.
- This allows the skates to glide smoothly over the snowy surface.
- The layer of water also helps to distribute the skater's weight more evenly, reducing the pressure exerted on the snow and preventing the skates from sinking too deeply into the snow.
**Conclusion:**
In summary, the formation of water below the skates when skating on snow is a result of an increase in pressure between the skates and the snow. This increased pressure decreases the melting point of the ice, causing it to melt and form a thin layer of water. This layer of water acts as a lubricant, allowing the skates to glide smoothly over the snowy surface. Therefore, the correct answer is option 'B' - Increase in pressure between skates and snow.

I think due to friction work done and work convert into heat that is use to increase in temp and ice melts so,....
