* Spacing of particles: In solids, particles are tightly packed together, with very little space between them. In gases, particles are much further apart and move freely.
* Mass vs. Volume: Because of the greater spacing in gases, the same amount of matter (mass) takes up a much larger volume compared to a solid.
* Density Calculation: Density is calculated as mass divided by volume. Since gases have a much larger volume for the same mass, their density is lower.
Example: Think of a balloon filled with air. The air inside the balloon is a gas. If you were to try to squeeze the balloon, you'd find that the air can be compressed because the particles are so far apart. A solid object like a rock, on the other hand, can't be compressed easily because its particles are tightly packed.
