How are the particles in a gas arranged?

• A. In a fixed structure and close together
• B. In a random arrangement and widely spaced
• C. In an orderly structure with some space
• D. In organized layers

Answer: (B)

The arrangement of particles in a gas is characterized by a random distribution and significant spacing between them. Unlike solids, where particles are closely packed in a fixed structure, gas particles are free to move independently of one another. This freedom of movement allows gases to expand and fill any available space, which is a fundamental property of gases. The random arrangement means that the particles do not have a specific order, and the wide spacing contributes to properties such as low density and high compressibility compared to liquids and solids. Thus, the correct understanding of gas behavior is that its particles are dispersed randomly and occupy a much larger volume compared to their size.
