SSC CHSL 2023 PYQ — Question 30

SSC CHSL - 07 Aug 2023 - Shift 1 • General Awareness • Q30

What is the state of matter that exhibits behaviour uniformity?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. Gas.

Gases exhibit uniform behavior due to their molecules being widely spaced, moving randomly in all directions, and expanding uniformly to fill any container.

Characteristics of Gases That Exhibit Uniformity:

  • Uniform Distribution: Gases spread evenly throughout a container, maintaining uniform pressure and concentration.

  • Compressibility: Gases can be easily compressed due to the large distance between particles.

  • Fluidity: Gases flow easily and conform to the shape and volume of their container.

  • Isotropic Behavior: Physical properties like pressure and temperature are consistent in all directions.

Why Not the Other Options?

Snow:

  • Heterogeneous—a mixture of solid ice crystals and air pockets, therefore not uniform.

Solid:

  • Fixed shape and rigid structure, with particles tightly packed and unable to move freely—does not exhibit uniform behavior.

Liquid:

  • Fluid but with limited compressibility, and molecules interact closely, leading to non-uniformity in some cases.
