Properties of Solids, Liquids and Gases

HideShow resource information
Why do solids not flow?
Because the particles are in a fixed, regular arrangement and do not move from their positions. There are strong bonds between the particles.

Why do solids have a fixed shape?
Because the particles are in a fixed, regular arrangement and do not move from their positions. There are strong bonds between the particles.
2 of 15
Why do solids have a fixed volume?
Because the particles are in a fixed, regular arrangement and do not move from their positions. There are strong bonds between the particles.
3 of 15
Why are solids difficult to squash?
Because the particles are already very close together and there is very little available space.
4 of 15
Why do solids have a high density?
Because there are lots of particles in a small volume.
5 of 15
Why do liquids flow easily?
Because although the particles are very close together, they can move past each other, though they do stick together.
6 of 15
Why do liquids have no fixed shape?
Because although the particles are very close together, they can move past each other, though they do stick together.
7 of 15
Why do liquids have a fixed volume?
Because there are bonds between the particles, though they are weak.
8 of 15
Why are liquids difficult to squash?
Because they are already very close together and there is very little available space.
9 of 15
Why do liquids have quite a high density?
Because there are quite a lot of particles in a small volume.
10 of 15
Why do gases flow easily?
Because there are very weak forces of attraction and no bonds between the particles, and they move quickly.
11 of 15
Why do gases have no fixed shape?
Because there are very weak forces of attraction and no bonds between the particles, and they move quickly.
12 of 15
Why do gases have no fixed volume?
Because the particles spread out to fill the container.
13 of 15
Why are gases not difficult to squash?
Because there are lots of free space between the particles.
14 of 15
Why do gases have a low density?
Because there are not many particles in a large volume.
