Answer:
Whether matter exists as a solid, liquid or gas is determined by the arrangement of its particles and the strength of attraction between the particles. The three states can be easily distinguished because of their physical properties.
A physical property is a characteristic of matter which can be observed without any chemical change to the matter (shape, volume, colour, smell etc.). A chemical change is one in which new substance are formed.
Explanation:
Solids have <u>a fixed volume and shape</u>. They also vibrate in a fixed position. Ice
Liquids have <u>do not have a fixed shape but a definite volume</u>. They take the shape of their container. They are able to move past each other by allowing the liquid to flow. Water
Gases <u>do not have a fixed shape or volume</u>. Particles take up the space of the container they are in. Particles move freely and rapidly. Water vapour
