Explain how the particle arrangement and movement differ between solids, liquids, and gases. How does this affect their ability to change shape and volume? (DRAW IT)
In solids, particles are packed tightly and only vibrate, so solids have a fixed shape and volume. In liquids, particles are close together but move around, allowing liquids to take the shape of their container while keeping the same volume. In gases, particles are far apart and move quickly, so gases spread out to fill the shape and volume of their container.
