Particle Arangement In solids, Liquids And Gasses

Question 1

Water exists as a solid, liquid and as a gas. What name is used for solid water and gaseous water?

Answer 1

Solid water is ice. Gaseous water is steam.

Question 2

Describe the arrangement and movement of the particles in a solid, liquid and gas.

Answer 2

In a solid, the particles pack together tightly in a neat and ordered arrangement. The particles are held together too strongly to allow much movement but the particles do vibrate. In liquids, particles are quite close together and move with random motion throughout the container. In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container.

Question 3

How are the particles in a solid arranged

Answer 3

The particles in solids are very close together, therefore they cannot usually be compressed or squashed. Forces of attraction between the particles hold them together and keep them in place.

Question 4

How are the particles in liquids arranged

Answer 4

The particles in liquids are arranged in a random way, and are close together, touching many of their neighbours. There are some gaps, but liquids cannot usually be compressed or squashed.

Question 5

How are the particles in a gas arranged

Answer 5

The particles in gases are widely spaced and randomly arranged, meaning they can be easily compressed or squashed.
