Sliding friction occurs when two solids rub against each other.
sliding
most likely the intermolecular forces. Solids have stronger intermolecular forces due to them being in closer proximity and contact between each other as opposed to liquids and gases.
Solids, in general (water is an exception),contain a higher concentration of thermal energy per unit volume than liquids ...and both solids and liquids contain a higher concentration that gasses.
The density of material depends upon the inter molecular force of attraction between the molecules... some solid molecules have more inter molecular force hence they are denser than other solids...

Sliding
there are strong forces holding the solids together so they cannot leave their positions.
Diffusion occurs with all molecules, but for many solids, it is an extraordinarily slow process at normal temperatures. Solids in contact with other solids may exchange a few molecules per second, and some may "jump back" again. The diffusion speed can be increased by raising the substances to high temperatures, giving the exterior molecules greater energy.
sliding
That is known as fragmentation.
If you are referring to Chilblains, Its kind of like an allergic reaction to extreme cold, its usually occurs when Ice and other cold objects are placed in contact with the skin. It is often mistaken for frostnip or frostbite. It can cause itching, blisters, and inflammation.
There different from each other because contact metamorphism is a local effect that occurs when molten rock meets solid rock, but on the other hand hydrothermal metamorphism occurs when very hot water reacts with rock, altering its mineralogy and chemistry.

short circuit occurs when two wire which consist of one live and neutral wire are in contact with the main and the other end of the wire are touched each other short circuit occurs
Contact forces are the ones which only when there is a contact between the two bodies where as a action at a distance force acts through imaginary things called fields which is set up when one of the body is placed in space irrespective of the other body.When an other body is placed within the boundaries of the field it gets influenced without actual contact between the two bodies.
