Short answer: You don't say what you are dissolving KCl (potassium chloride) in but we'll assume it is water. Salts like KCl dissolve in water better at higher temperatures. Boiling water (100C or 212 F) is the hottest you can get water without confining it and increasing the pressure. So 212F or 100C is the temperature that KCl is most soluble in water.
Longer answer: As you add KCl to water the boiling point of the solution becomes lower. So the real maximum solubility temperature (assuming no pressurization) is less than 212 F (100 C). The easiest way to measure this would be to mix highly purified KCl with highly purified water and boil it to see what the boiling temperature is. You must add enough KCl so that even at boiling temperature you still have some solids left that way you will have a saturated solution which will have as much KCl dissolved as the water can hold.

Are most solutes soluble at higher tempretures?
Practically all solid solutes are more soluble at high temperature.
Is Potassium nitrate a solid?
Corrected answer:NO,MOST of the potassium salts and ALL of the nitrates are SOLUBLE, not insoluble!!!So potassium nitrate is NOT INsolubleSome potassium salts and complexes are insoluble like Potassium Hexanitritocobaltate(III) = K3[Co(NO2)6] , etc.
What is the state of NaCO3?
Most nitrates are solid with good water solubility
