Question: What happens to the density of a material when it is compressed? (2019)
Options:
It decreases
It increases
It remains the same
It becomes zero
Correct Answer: It increases
Exam Year: 2019
Solution:
Density increases when a material is compressed, as mass remains constant while volume decreases.

What happens to the density of a material when it is compressed? (2019)
Step 1: Understand what density is. Density is the amount of mass in a certain volume. It is calculated using the formula: Density = Mass / Volume.
Step 2: Know that when a material is compressed, its volume decreases. This means the space the material takes up gets smaller.
Step 3: Remember that the mass of the material stays the same during compression. The amount of material does not change.
Step 4: Since the mass is constant and the volume decreases, the density must increase. This is because you are putting the same amount of mass into a smaller space.
Density – Density is defined as mass per unit volume, and it increases when the volume decreases while mass remains constant.
