Q: When a solvent with a gas dissolved in it is heated, the kinetic energy of both the solvent and solute _________?


Read this paragraph and choose the correct option from the provided answers:

Several substances – HCl, NH 3 , and SO 2 – have solubility that decreases as temperature increases. They are all gases at standard pressure. When a solvent with a gas dissolved in it is heated, the kinetic energy of both the solvent and solute increases. As the kinetic energy of the gaseous solute increases, its molecules have a greater tendency to escape the attraction of the solvent molecules and return to the gas phase. Therefore, the solubility of a gas decreases as the temperature increases.

 Choices:

- evaporates

- generates

- decreases

- increases


A:
increases
