(b) Why do solids, liquids and gases differ in
their physical state ?
Answers
Answer:
Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.

Answer:
Depends on the arrangement of molecules in a solid liquid or gas....
In solid, it is densely packed does not freely allow movement of molecules....
in liquids, there are few gaps between molecules and therefore are somewhat less rigid than solids but more rigid than gases..
In gases, there are huge spaces between each molecule and hence not at all rigid
Explanation:
1.Solid
Solids have a set shape and volume. In a solid, the particles are more closely arranged. The particles have less net movement. Solids are rigid, meaning that the particles are “locked” into place. Solids are not easily compressible, given that they have a set volume. Solids do not flow easily, because the particles are rigidly connected and do not move past one another.
2.Liquid
Liquids have a set volume, but they can change shape depending on what container they are in. The particles in a liquid move more freely within the set volume. Liquids do not form structures like solids, because of the intermolecular movement. Liquids are also not easily compressible, because of the set volume. Liquids flow easily because the particles are able to move past each other easily.
3.Gas
Gases can change shape and volume. Gas particles will spread out as far as they need to in order to fill the container. They will take the shape and volume of whatever container they're in. They are easy to compress because there is a lot of space between the particles. It also flows easily because of the amount of space between particles.
