potassium nitrates energy is just a little bit higher than water at room temperature. its what is called an "endothermic reaction" which means it requires heat. when heated, more energy is introduced to the system which allows it to dissolve quicker.

Most solids do that. Think of the small particles of solid having energy and moving around. The hotter it gets, the more energy they have and the more they move. The more movement, the more water molecules can mix in, so more is dissolved

Because the heat gets the particles moving more and, following the kinetic motion theory, causes them to react more readily, in this case dissolving.

because its mass expands which allows for more surface area to be dissolved. also extreme temperatures help dissolve anything
