salt grains are groups of oppositely charged ions in a tight solid pattern. When they dissolve the water molecules attract these ions and cause them to separate, becoming a solution.
It was dissolved
Sand grains will not dissolve in water. Therefore, sand and water can not form a solution. Salt and water can make a (saline) solution, because the salt crystals will dissolve completely into the water.
Heat the water to boiling point, then put the rock sugar in
Soluble describes something that can be dissolved in water. Insoluble describes something that can not be dissolved in water. Salt is soluble, it will dissolve in water. Oil is insoluble, oil will float on the surface of water.

no, corn starch cannot dissolve in water. The grains (particles) that are in the cornstarch are "suspended" in the water and cannot totally dissolve in the water.
The water dissolve
It was dissolved
yes there was

Neither grains of rice, or lentils (an edible pulse), are soluble even when boiled until soft in water.
Heat the water to boiling point, then put the rock sugar in
Yes there is a change in volume.
hydrophilic
salt does not disolve quickly in water because all the little grains are so small the have more suface area than air bubbles therefore the water takes longer to get into the grains of salt.
Dissolving is a physical change.
