What happen when two ice is rubbed immediate?

When two pieces of ice are rubbed together immediately, several interesting phenomena occur:

1. Pressure Melting: When the two ice surfaces come into contact, the pressure at the interface increases significantly. This high pressure causes the ice to melt at the point of contact, creating a thin layer of liquid water between the surfaces.

2. Adhesive Forces: As the ice surfaces continue to rub, the liquid water layer facilitates the formation of adhesive forces between the two pieces of ice. These adhesive forces arise due to the intermolecular interactions between the water molecules at the interface.

3. Friction Reduction: The presence of the liquid water layer drastically reduces the friction between the ice surfaces. This reduction in friction allows the two pieces of ice to glide more smoothly against each other.

4. Regelation: As the pieces of ice are rubbed further, the liquid water layer refreezes and bonds the two surfaces back together. This process is known as regelation and is driven by the release of latent heat as the liquid water solidifies.

5. Surface Roughening: The continuous rubbing of the ice surfaces creates scratches and grooves on the ice, roughening the surface texture. This surface roughening can further enhance the adhesive forces and regelation process.

6. Ice Shavings: Under sufficient pressure and friction, the rubbing of ice can also produce ice shavings or fragments. These fragments are formed as the adhesive bonds between the ice crystals fracture due to the applied forces.

The combination of these effects during the rubbing of ice leads to reduced friction, bonding of the ice surfaces, and the formation of ice shavings.
