In general, the solubility of most solid solutes in water increases with temperature. However, there are exceptions, particularly with gases.
Among the substances listed:
1. **Sodium chloride crystals (NaCl)**: More soluble in warm water than cold water.
2. **Oxygen gas (O2)**: Gases are typically more soluble in cold water than in warm water because warmer water can hold less gas due to increased kinetic energy, which allows gas molecules to escape more readily.
3. **Potassium chloride salt (KCl)**: More soluble in warm water than cold water.
4. **Sugar powder**: More soluble in warm water than cold water.
Thus, **oxygen gas** is the substance that would be more soluble in cold water than in warm water.
