Question

part a describe the shape of the graph. what does the shape say about the relationship between mass and volume?

Explanation:

If the graph of mass vs volume is a straight - line passing through the origin, it indicates a direct proportionality between mass and volume. The slope of the line represents the density of the substance. If the graph is a curve, it implies a non - linear relationship between mass and volume.

Answer:

If the graph is a straight line through the origin, mass and volume are directly proportional. If it is a curve, the relationship is non - linear.
