Extrusive igneous rock is formed from rapidly cooled lava at Earth's surface. Examples are obsidian and basalt.
If a substance is cooled and solidified rapidly, generally amorphous material is obtained instead of crystals. In order to obtain good quality crystals, if is better that the substance solidifies slowly
In the normalising metal treatment process, the metal is cooled slowly and gradually while in quenching metal treatment process the metal is called very fast and abruptly.
scoria
Yes. Rapid cooling of molten rock produces small crystals.
Pasteurisation is a process where food items are heated very rapidly for a few seconds to kill bacteria and then rapidly cooled again. I think the temperature has to reach 65-70 degrees Celcius to be effective.
When steam is cooled in the air, you can see it condensing into a mist. This process is called condensation.
The process would be called evaporation.
It depends on the amount of carbon the metal has. If the metal has too much carbon than it will become brittle. If it doesn't then it will harden. (A lot of tools go through this process called Tempering)

Tempering is the process to add properties to the raw glass and to make it Standard or Toughened. If tempered (Heated) and cooled slowly, it becomes standard glass on the other hand if tempered and cooled rapidly, it gains different properties and becomes tough or is called toughened glass. Check the link below.
It's called condensation when vapour cools and turns into liquid.
The process is called condensation. It occurs when the water is cooled below its boiling point due to the temperature in the environment cooling it.
Extrusive igneous rock is formed from rapidly cooled lava at Earth's surface. Examples are obsidian and basalt.
It takes only a few seconds to make a water bottle. Liquid plastic is injected into a mold which is rapidly cooled to reveal a completed bottle minus the cap.
Evaporation. A body of water is cooled as a portion of it is converted to vapor by evaporation.
They heated iron ore, hammered it, and rapidly cooled it.
