A. The solute is a SOLID because the amount dissolved DECREASES as temperature increases.

B. The solute is a SOLID because the amount dissolved INCREASES as temperature increases.

C. The solute is a GAS because the amount dissolved INCREASES as temperature increases.

D. The solute is a GAS because the amount dissolved DECREASES as temperature increases.

To determine the type of solute in the given solution based on the provided table of temperatures and concentrations, follow these steps:

1. Analyze the given data:
- Temperature ([tex]$^{\circ}C$[/tex]): 20.5, 30.1, 40.3, 51.0
- Concentration (g solute/mL solvent): 0.772, 0.835, 1.03, 1.09

2. Observe the trend in concentrations as temperature increases:
When we examine the concentration values:
- At 20.5°C, the concentration is 0.772
- At 30.1°C, the concentration is 0.835
- At 40.3°C, the concentration is 1.03
- At 51.0°C, the concentration is 1.09

We see that the concentration increases as the temperature increases.

3. Determine the type of solute based on the trend:
- For a solid solute, the solubility (amount dissolved) typically increases as the temperature increases.
- For a gas solute, the solubility (amount dissolved) typically decreases as the temperature increases.

4. Conclusion:
Since the concentration increases with an increase in temperature, it indicates that the solute is a solid.

Therefore, the correct statement is:
- The solute is a SOLID because the amount dissolved INCREASES as temperature increases.
