Why solid has a fixed shape? |
According to kinetic particle theory, the particles of a solid are closely packed in an orderly and regular manner, are held together by very strong forces of attraction, have enough kinetic energy to only vibrate and rotate about their fixed positions and cannot move around freely. They also cannot be compressed as its particles are very close to one another. |

Why liquid takes the shape of their container? |
According to kinetic particle theory, the particles of a liquid are quite close through slightly further apart than in solid and are arranged in disorderly manner, have more kinetic energy than solid and are not held in fixed positions and they slide over each other and can move freely throughout the liquid. The particles are further away from each other than particles of solid. However, they are still packed quite closely together and liquid cannot be compressed. |

Why gas take the shape if their container? |
According to kinetic particle theory, the particles of a gas are spread far apart from each other, have very weak forces of attraction, have a lot of kinetic energy and are not held in fixed positions and can move freely in all directions at high speed. The particles have a lot more space between them and the large space between them allows the gas to be easily compressed when pressure is applied. |
