The following actions will increase the solubility of a solute:
1. **Stirring the solution** - This helps to distribute the solute more evenly throughout the solvent, facilitating dissolution.
2. **Heating the solution** - For most solid solutes, increasing the temperature generally increases solubility, as it provides more kinetic energy to break solute-solute interactions.
3. **Increasing the surface area of the solute** - By increasing the surface area (such as crushing solids), more solute particles are exposed to the solvent, which can enhance the rate of dissolution.
The other options would not increase solubility:
- **Decreasing the surface area of the solute** - This would hinder dissolution, not enhance it.
- **Cooling the solution** - This typically decreases the solubility of solid solutes, though it may increase the solubility of gases.
So, the correct selections are: **stirring the solution, heating the solution, and increasing the surface area of the solute.**
