The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Solubility**: - Solubility refers to the amount of solute that can dissolve in a specific volume of solvent (in this case, water). 2. **Identifying Factors**: - The two main factors that affect the solubility of a solute in water are temperature and pressure. 3. **Effect of Temperature**: - When the temperature of the water increases, the solubility of most solid solutes also increases. This means that more of the solid can dissolve in the water at higher temperatures. 4. **Effect of Pressure**: - Pressure primarily affects the solubility of gases in liquids. Increasing the pressure above a liquid increases the solubility of a gas in that liquid. This is because higher pressure forces more gas molecules into the liquid. 5. **Conclusion**: - Therefore, the two factors that affect the solubility of a solute in water are **temperature** and **pressure**. **Final Answer**: Temperature and pressure affect the solubility of a solute in water. ---
