fast cooling rate forms smaller crystals eg Andesite
slow cooling rate forms large crystals eg.Pegmatite
The rate of cooling is the speed at which magma or lava crystallizes. When the speed is slow it results in big crystals. When the speed is fast it results in small crystals.
The speed at which the magma/lava cools ie. fast cooling = not much time for crystals to form = little or no small crystals slow cooling = much time for crystals to form = big crystals
It depends on the cooling of lava. Slow cooling forms big crystals deep under the surface while fast cooling creates small crystals on or just below the earths surface. Itstant cooling wouls have no crystals.
The most common effect is that more and smaller crystals form than would be formed with slow cooling of the same mass of the same crystalizable material, and the incidence of crystal defects is higher because the rapidity of crystal formation does not permit the correction of initially formed defects by interchange of atoms or other crystal forming units between the liquid and solid phases that can occur during slow crystallization.
a higher wind speed causes the saturated air around the sweating object to be dislocated and thus the sweating process, evaporation of water molecules, will be more efficient.
The speed in which a molten rock is solidified, determines the size and type of crystals.

yes
Think about this: When molten rock cools slowly, bigger crystals are created.Then think about this: Intrusive rocks cool quite slowly because they are created in the earth's crust.So... Intrusive igneous rocks have bigger crystals. Molten magma in the earth's crust cools slowly making rocks like granite with big crystals.Get it? got it?GOOD!!
The quicker the wind speed is the faster the object will cool that's because of the temperature change is greater when the speed of win is greater.
That's because of the cooling speed. When a magma or a lava cools, it forms crystals. The longer these crystals have the time to form, the larger they will be. However, at the surface, the lava cools relatively fast (at least, compared to magma that stays inside the earth). The crystals in the rock that forms that way don't have a lot of time to form, so don't grow big.
Virtually all rock contains mineral crystals of various sizes. Most volcanic rocks such as granite contain crystals of quartz and other minerals. Crystal size varies depending on the speed of cooling.

A fan or cooler relay is used in electrical furnace to change the blower speed to the blank speed for cooling
