hope this helps!
I’m going to say Gravity.
The solubility of substance depends upon the temperature. In present case, the solubility of KCl is 84g/100g at <span>50.oC.
This means that, maximum 84g of KCl can be dissolved in 100g of water (at </span>50.oC) to form solution. This solution is referred as saturated solution.
Thus, 84g of <span>KNO3 must be dissolve in 100 grams of water to form a saturated solution at 50 oC.</span>
The answer to your question is liquid hydrogen
