###### Problem Details

Part A. By varying the mass and volume parameters, determine how the density is affected by the following changes.

a. Increasing the mass while keeping the volume constant

b. Decreasing the mass while keeping the volume constant

c. Multiplying the mass and volume by the same factor

d. Decreasing the volume while keeping the mass constant

e. Increasing the volume while keeping the mass constant

f. Dividing the mass and volume by the same factor

Density is a measurement of an object’s ratio of mass per unit of volume:

density = mass/ volume

It is considered a temperature-dependent measurement since many substances’ volumes change along with changes in temperature. It should not be confused with weight since weight depends on a gravitational field, whereas density relies upon mass and volume alone (two properties obtained by measurements that remain the same despite the presence of a gravitational field).
