The size of the crystals that do form are smaller/microscopic in that the time an temperature for crystals to grow is cut. The type of mineral that crystallizes is also effected,

How does the speed of cooling of molten rock affect the size of crystals that form?
fast cooling rate forms smaller crystals eg Andesiteslow cooling rate forms large crystals eg.Pegmatite
As the rate of cooling of igneous rocks increases the size of the crystals that form?
The size of crystals decreases as the cooling increases. This is called an inverse relationship.
. As the rate of cooling of igneous rocks increases the size of the crystals that form?

How does the crystal sizes of igneous rocks indicate the rate of cooling and whether the rock is extrusive or intrusive?
Generally, large crystals represent slow cooling rates and small crystals represent fast cooling rates. Crystals need time to form and since extrusive rocks cool very quickly, they have very tiny crystals and some don't even have crystals because the rate of cooling was so fast that crystals didn't have time to nucleate. On the other hand, intrusive rocks cool rather slowly allowing crystals to grow.
How are crystals formed and how does the rate effect the crystal?
Crystals that are formed below the surface are formed by the cooling of magma. Crystals above the surface are formed when a volcano erupts, and cools, again, above the surface. Crystals that are below the surface usually have a slower rate of cooling than those above the surface, causing bigger crystals because of the slower cooling:)

What are the conditions which small and large crystals are likely to form?
Large crystals form when a rock cools from magma slowly whereas smaller crystale form when there is a slow rate of cooling
What determines the size of crystals that form in granite?
The cooling rate of magma plays a significant role in determining the size of crystals.
What rate of cooling produces the largest crystals in igneous rocks?
A slow rate of cooling. The slower a magma cools, the longer the crystals have to grow, thus the bigger they will be.

Explain pegmatite is coarse grained with large crystals basalt is fine grained with small crystals and obsidian has no crystals?
Crystal size in these rock types is determined by their rate of cooling. Pegmatites have large crystals due to very slow cooling. Obsidian has microscopic crystals due to almost instantaneous cooling.
How does the rate of cooling affect the size of copper sulphate Chrystals?
larger crystals
What is the rate of cooling in reference to magma and lava?
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.
