How can you make pure crystals of alum from impure alum?
To make pure crystals of alum from impure alum, start by dissolving the impure alum in warm water. Filter the solution to remove any impurities, and then cool the filtered solution slowly. As the solution cools, pure alum crystals will start to form. Carefully collect the crystals and allow them to dry to obtain pure crystals of alum.
Were does an igneos rock start off?
it is from the magma solidifieing under ground when there is an eruption it can also happen when the volcano is overflowing. whaty happens is that the magma cools the little crystals and bits of rock which makes them interlocking and a solid rock
How are solvent and solute alike?
The "solute" is the item that is dissolved in the "solvent".
Why magma floats to the surface?
Magma would float to the top for a certain amount of time because it's hotter than water. But when it cools down it will start to sink.
How does the amount salt affect salt crystal growth?
I think it's because salt dissolves better in hot water than cold water, so as the solution cools the salt wants to come out of solution and crystallize. When you pour the solution over the sponge, this causes the liquid to evaporate. This further concentrates the salt so that it will crystallize. The salt crystals will start to form on undissolved salt or on the sponge. Once the crystals start forming, they grow fairly rapidly...

Why is cold solvent used to wash crystals after the mother liquor is removed?
Usually, solvents at lower temperature can dissolve lower amount of crystals than solvents at higher temperatures. For eg. if impurity is salt then you are better off washing it at a lower temperature as salts have a good solubility even at lower temperatures and as you raise temperature your crystals will start dissolving in the warm solvent.
What size crystals result from fast cooling?
When a magma cools down, it becomes a solid. Various atoms "prefer" to be arranged in a crystallic way. So when a magma cools down, crystals start to form and grow. Crystals only grow at their edges, so to make the crystal grow larger, it would need more time to do so. Magma's that cool slower have more time for the crystals inside them to grow, so the crystals will be larger, compared to a magma that cools quicker, or even a magma that comes out of the ground (then called a lava).

Size of crystals made by slow cooling?
because the crystals gradually start to melt.
Car starts and drives fine but when it's turned off it won't start until it cools?
car start and drives fine bu when its turned off it wont start until it cools?
How do geode start out?
they start hallow without any crystals inside.
How do you restart your car after vapor lock?
Once it cools off it will start.
How does water get cold?
Water cools to the environment around it. a lake will have water colder in the deeper areas while warmer at the surface. Water in a refrigerator cools to the inside of the fridge because the inside temp is the surrounding that the water chills to.
Will a car start if it has over heated?
After it cools if there was no damage sustained during overheating
How are solvent and solute alike?
The "solute" is the item that is dissolved in the "solvent".
