Which of the following changes will increase the amount of solid solute able to be dissolved in a liter of liquid water?

decreasing pressure
increasing temperature
decreasing temperature
increasing surface area

Option (b) is the correct answer.

Explanation:

For a solid solute, when we increase the temperature then the molecules of solid will start to vibrate.

As a result, the force of attraction between the molecules will decrease and molecules can easily start to move from one place to another. Hence, the solute will start to dissolve in the solvent.

Thus, we can conclude that on increasing the temperature will increase the amount of solid solute able to be dissolved in a liter of liquid water.
