A supersaturated solution _____. a. is one that has been heated b. must be in contact with undissolved solid c. is one with more than one solute d. is one with a higher concentration than the solubility. Answer is: 1) high pressure and low temperature. Let's explain each parameter or change separately. A) Regarding change in pressure and its effect on the solubility of a gas in a liquid, this can be explained by Henry's law which states that: "At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly. Detailed Solution for Test: Solubility - Question 5 The correct answer is option A According to Henry's law, solubility of a gas in a liquid is directly proportional to pressure of gas. P αX P=K H X P= Partial pressure of gas X= solubility of gas in liquid KH = Henry's constant. 1 Answer to   MULTIPLE CHOICE   1.A lipid is any substance of biochemical origin that is a.insoluble in nonpolar solvents but soluble in water b.insoluble in both water and nonpolar solvents c.insoluble in water but soluble in nonpolar solvents d.soluble in both water and nonpolar solvents  .
