Question

Abvole is a graph of mass versus volume for iron. The density of iron is equal to the slope of the graph.

Is the graph consistent with what you know about density?

a) Yes, the density is constant, therefore as the mass increases, the volume increases.

b) No, the density is constant, therefore as the mass increase, the volume decreases.

c) Yes, the density is constant, therefore as the mass increases, the volume decreases.

d) No, the density varies, therefore the volume is not directly proportional to the mass.

Explanation / Answer

Answer:- A

Density of a substance is approximately constant. And we know that density is mass per unit volume so for density to remain constant as mass increase volume should also increase and vice versa.

So the graph of mass vs volume should be a straight line having constant slope as the slope of graph gives density of substance.
