Question

Why do gases mix easily, while solids do not?

Show answer Hide answer
Answer
Gas particles move freely, so they mix easily.

Explanation

  • Gas particles have negligible attraction and move freely.
  • They spread and fill all space, so they mix easily.
  • Solid particles are tightly held in fixed positions.
  • They cannot move around, so solids do not mix.
Free-moving gas particles mix easily, but tightly fixed solid particles cannot.
