What is the colour of copper sulphate crystals before and after heating?
Copper Sulphate crystals before heating r blue....but after heating I dunno , may be u should try and ask your Sci.Miss/Sir I'll get back when I get the other answer .
What does grain-size tell you about the cooling history of a rock?
Slower rates of cooling will create larger crystals. Rapid cooling allows little time for element accumulation in the crystal, therefore, the crystals created will be smaller. Larger, visible crystals in igneous rock indicate that the magma was slow cooling, usually at depth. Much smaller crystals in igneous rock indicate rapid cooling of lava, usually at or near the surface. Crystals in igneous rock will grow larger and have more time to accumulate material for their growth the more time they have at their crystallization temperature.
What are Ghost crystals?
Ghost Crystals are crystals of crosslinked polyacrylamide.
Are crystals living or nonliving?
NO CRYSTALS are not living!!!!!!!!!!!!!!!!!
Why do some igneous rocks have larger crystals but other igneous rocks have crystals so small they have to be seen with a microscope?
Crystal size in igneous rock is dependent on the amount of time spent in cooling from magma or lava. More time means larger crystals. Rocks that have small crystals cooled quickly, so the minerals didn't have time to rearrange and form large crystals before the rock solidified. These small-crystalled rocks are described as aphanitic. Other rocks cooled slowly, so the minerals had time to rearrange and form large crystals before solidifying. These rocks are considered phaneritic. Some rocks cool slowly for a while, and then experience rapid cooling (such as magma that cools slowly inside a volcano, and then cools rapidly when the volcano erupts). Such rocks have large crystals surrounded by tiny crystals. Rocks that form this way are described as porphyritic.
Can you see crystals in basalt?
Not usually unless you have a microscope. Crystals in baslat are usually microscopic. However, in some cases basalt may have a porphyritic texture, where some minerals in the magma have started to crystallize before the eruption.

What is an igneous rock with crystals?
Granite with larger crystals, basalt with smaller crystals.
What do you do on a science fair about crystals?
you should talk about how crystals are formed and what type of crystals there are
Can salts form crystals?
Yes. Salts can form crystals (salt crystals).
What is given to ice crystals that move up and down in a thunderstorm and get larger and larger before they fall to earth?
It evaporates
