Question

Assuming all other conditions remain the same, which of the following will cause and object's density to increase?

A. Its mass increases
B. Its volume decreases
C. Its atoms move closer together
D. All of the above

Answer 1

D. All of the above

Step-by-step explanation:

When an object's density increases, it means that more mass is packed into a given volume. There are three factors that can cause an object's density to increase:

1. If the mass of the object increases while the volume remains the same, the density will increase because there is more mass in the same amount of space.

2. If the volume of the object decreases while the mass remains the same, the density will increase because the same mass is compressed into a smaller space.

3. If the atoms of the object move closer together while the mass and volume remain the same, the density will increase because the same mass is concentrated in a smaller volume due to the reduced spacing between the atoms.
