Question

The equation for density is mass divided by volume. An increase in density can result from all of the following except _______.

Answer 1

Answer: A. a decrease in mass with an increase in volume

Explanation:

Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{volume}$

Thus density has direct relationship with mass and inverse relationship with volume.

Thus increase in mass leads to increase in density and increase in volume leads to decrease in volume.

A. a decrease in mass with an increase in volume will lead to decrease in density.

B. an increase in volume with an increase in mass will have no change in density.

C. a decrease in volume with no change in mass  will lead to increase in density

D. an increase in mass with no change in volume will lead to increase in density

Answer 2

I think the correct answer from the choices listed above is option A. The equation for density is mass divided by volume. An increase in density can result from all of the following except a decrease in mass with an increase in volume.
