These are two different methods that are opposites. Surface hardening is used to stiffen a steel. Usually a steel is heated, a catalyst is applied to the surface and then the steel is quenched in an oil bath or waterbath, this hardens the surface of the steel. Annealing on the other hand, the steel is heated and then allowed to cool slowly. This softens the steel and allows it to be drawn or hammered to form a different shape.

because water has a surface tension that likes to hold together. How much it takes to hold it together is based on what incline it is on. In this case, wave patterns are observed because the surface tension keeps a larger amount of water in one place, until the weight overcomes the surface tension, and it creates the wave pattern you see.

True. When light reflects off a rough surface, the reflection is diffuse, meaning the light rays scatter in different directions. This is in contrast to a smooth surface where the reflection is more specular, and the light rays travel in a predictable direction.
Why do they have different surface temperature
The surface is open to the exterior.
yes, of course different surface different amount of friction
