What is the primary difference between the particles of a solid and those of a gas?
Solid particles are more closely packed than gas particles.
The primary difference between solid and gas particles is their arrangement. Solid particles are tightly packed, allowing them to maintain a fixed shape, while gas particles are loosely arranged and can move freely. Hence, the correct answer is that solid particles are more closely packed than gas particles.
