it all depends on which crystals you mean, salt crystals can dissolve in both hot and cold water they dissolve quicker in hot water as the hot water acts as a catalyst for this
yes
they dissolve but water will become saturated that's why the remaining Iodine crystals will remain suspended.
They dissolve - relatively slowly.
Some crystals do, such as sugar. Others, like salt, don't depend on the temperature of the liquid. All crystals are different.

yes
Jelly crystals do dissolve in water. They dissolve faster in hot water than cold. The hot water breaks down the Gelatin that makes up the jelly.
because the substance in the potassium permanganate crystals are permeable to water, so that means it will dissolve instantly while poured into water Save

it is all about surface area. if you were to stir it the sugar crystals would have water on all sides, but when sitting in the bottom of a cup the water has to dissolve the crystals on the outside, and then it would keep going.
Correct.
it breaks up into individual crystals.
Table salt is made of many tiny crystals. When you mix these salt crystals with water, they dissolve, losing their crystalline form. When the water evaporates, the salt crystals form once again.
Well copper sulphate crystals can be dissolved in water so when dissolved you filter the solution to remove the broken glass then evaporate the water then collect the crystals or crystallisation.
They dissolve - relatively slowly.
Dissolve sugar in hot water until you can't dissolve any more. Then wait for the sugar water to evaporate. You can hang a piece of yarn into the sugar water; the crystals should form around the yarn.
