What happens to the density of a solid when it is subjected to uniform compression? (2020)

Step 1: Understand what density is. Density is the mass of an object divided by its volume.
Step 2: Know what happens during uniform compression. Uniform compression means applying pressure evenly on all sides of the solid.
Step 3: Realize that when a solid is compressed, its volume decreases. The particles in the solid are pushed closer together.
Step 4: Since the mass of the solid remains the same (it doesn't lose or gain mass), but the volume decreases, the density must increase.
Step 5: Conclude that when a solid is subjected to uniform compression, its density increases because density is mass divided by volume.

Density and Compression – When a solid is uniformly compressed, its volume decreases while its mass remains constant, leading to an increase in density.
