Question
**Figure 4: Mass and Volume Relationships**

The graph titled "Mass and Volume Relationships" represents the relationship between the mass (in grams) and volume (in milliliters) for two substances, labeled A and B.

**Graph Details:**
- The x-axis represents volume in milliliters (mL), ranging from 0 to 80 mL.
- The y-axis represents mass in grams (g), ranging from 0 to 80 g.
- Two lines are drawn on the graph:
  - Substance A has a steeper slope than Substance B.
  - Substance B has a less steep slope.

**Questions:**
a) Which substance is more dense, substance A or substance B? Explain your reasoning.

b) Find the slope of the line for both A and B using correct units. State the physical meaning of the slope ("For every...") for each substance.
   - Slope A: \((Y_2-Y_1) / (X_2-X_1)\) =
   - Slope B: \((Y_2-Y_1) / (X_2-X_1)\) =
   - For every...

c) Water has a density of 1.00 g/mL. Draw the line representing water on the graph in Figure 4.

d) Determine whether substance A and B will sink or float when placed in a bucket of water.
   - Substance A: sink / float
   - Substance B: sink / float
