The question asks about the solubility of two substances (A and B) at different temperatures, and the data provided helps in determining the solubility behavior.

### Part 1: Which, if any, substance is soluble in water?
- **Substance B** is soluble in water because the mass of undissolved Substance B decreases as the temperature increases. Specifically, at 20°C, 10 grams remain undissolved, and this decreases to just 2 grams at 80°C.
- **Substance A**, on the other hand, shows no change in the amount of undissolved substance across all temperatures (50 grams undissolved at every temperature). This suggests that Substance A is not soluble in water across the given temperature range (20°C to 80°C).

### Part 2: How the data helped determine solubility for both substances between 20°C to 80°C?
- **Substance A:** The data shows that the mass of undissolved Substance A remains constant (50 grams) at all temperatures. This indicates that the substance does not dissolve in water, regardless of the temperature.
  
- **Substance B:** The mass of undissolved Substance B decreases as the temperature rises, from 10 grams at 20°C to just 2 grams at 80°C. This suggests that increasing the temperature improves the solubility of Substance B in water, as more of the substance dissolves at higher temperatures.

Would you like further clarification on any part? 

Here are 5 related questions to deepen understanding:
1. How does temperature typically affect the solubility of solids in liquids?
2. What other factors, besides temperature, can affect solubility?
3. Why might Substance A be completely insoluble in water?
4. Could there be a temperature higher than 80°C at which Substance A becomes soluble?
5. How would you design a similar experiment to test the solubility of gases in water?

**Tip:** Solubility generally increases with temperature for most solids in liquids, but this pattern can vary depending on the specific substance.

Matt did an experiment to study the solubility of two substances. He prepared 100 mL of water at 20°C into each of two beakers labeled A and B. He put 50 g of Substance A in the beaker labeled A and 50 g of Substance B in the beaker labeled B. The solution in both beakers was stirred for 1 minute. The amount of substance left undissolved in the beakers was weighed. The experiment was repeated for different temperatures of water, and the observations were recorded as shown.

Explore how the solubility of two substances changes with temperature in this experiment. Substance B becomes more soluble as temperature increases, while Substance A remains insoluble. Detailed data and explanation provided for grades 6-8.
