Step 1: Understand what volume means. Volume is the amount of space an object takes up.
Step 2: Know what solid means. A solid is a state of matter that has a definite shape and volume.
Step 3: Learn about pressure. Pressure is the force applied to an area.
Step 4: Recognize what uniform pressure means. Uniform pressure is the same pressure applied evenly across the entire surface of the solid.
Step 5: Understand the concept of bulk modulus. The bulk modulus is a measure of how much a material can be compressed when pressure is applied.
Step 6: Realize that when uniform pressure is applied to a solid, the particles in the solid are pushed closer together.
Step 7: Conclude that as the particles get closer, the volume of the solid decreases.

Bulk Modulus – The bulk modulus is a measure of a material's resistance to uniform compression, indicating how much the volume decreases under pressure.
