Yes they will
When molten rock cools slowly, it will have a lot of time to form crystals, so the crystal size will be quite big. Take granite, for example. With the naked eye, you can see the individual crystals. The grain size is quite large. The kind of mineral that forms is dependent on the composition of the magma.
Small crystals are likely to form when the solution cools quickly or when there are impurities present that inhibit crystal growth. Large crystals are likely to form when the solution is allowed to cool slowly or when there is a high concentration of solute in the solution.
Crystals are generally formed when magma or molten rock cools and solidifies. Rapid cooling of the molten rock generally results in the formation of small crystals, like when magma reaches the surface. However, if they cool down slowly, then large crystals are formed. Keeping heat applied allows more growth on the crystal over time. In that logic, larger crystals grow underground.
Extrusive rocks are formed from magma that cools quickly on the Earth's surface, resulting in small crystals or glassy texture. Intrusive rocks are formed from magma that cools slowly beneath the Earth's surface, resulting in larger crystals due to slower cooling. These differences in cooling rates affect the texture and appearance of the rocks.

Generally speaking, yes. Magma that cools quickly will produce small, "fine grained" crystals.Magma which cools slowly will generally produce rocks with larger, visible to the naked eye, crystals.This is because while magma is cooling, crystals are forming. Generally, crystal which have more time to grow will be larger. Therefore, generally, the slower magma cools, the bigger the crystals will be. The faster lava cools, the less time crystals have to grow and are thus smaller, "fine grained".
The rate at which the magma cools affects the size of the crystals that form. If it cools slowly, large crystals will form. If it cools rapidly, small crystals will form.if it takes the rock a long time to cool down the crystals will be bigger if the rock takes a short time to cool the crystals will be smaller

It depends on the cooling rate of the magma. If the magma cools slowly underground, large crystals can form, creating intrusive igneous rocks. If the magma cools rapidly on the Earth's surface, small crystals or glassy textures can result in extrusive igneous rocks.
It is true that lava cools quickly and forms minerals with small crystals.
Usually from the slow cooling of magma with a plentiful supply of material necessary for crystal growth, and space in which to grow.
The rock is called porphyry, which forms when magma slowly cools beneath the Earth's surface. The large crystals are known as phenocrysts, and the smaller surrounding crystals are called groundmass or matrix.

The size of the mineral crystals in an igneous rock is related to the rate of time spent in cooling from magma. Longer exposure to the crystallization temperature means larger crystals. Less time means smaller crystals, or in the case of obsidian, which cools extremely quickly, no crystallization.
