The correct answer is dissolving and the end product is a solution.
Explanation:
Solubility is an property of a substance to get dissolved into another. When a substance, termed as solute, dissolves in another substance, termed as solvent, we get a solution.
Larger molecules of the solute breaks because of weak covalent bonds between their molecules and pairs up with the smaller molecules of the solvent and thus dissolves in it. Not all elements can serve solutes or solvents as some have strong forces that bind them together. For example sugar is a solute in water but oil is not soluble in water.

From dynamics we know that the formula for average velocity is:
a) For the three intervals:
b) The average velocity for the entire motion can be calculate by the following formula:
Well it depends on what kind of liquid, some liquids if you heat it up itll turn into a solid, but most just turn into a gas
