It begins: Everything around us is made of matter: anything that has mass and takes up space, even the air. --- [Mova](https://md.mova.elamur.ai/free/en/) · [this page in HTML](https://mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/) [home](https://md.mova.elamur.ai/free/en/) / [corpora](https://md.mova.elamur.ai/free/en/corpora/) / [school](https://md.mova.elamur.ai/free/en/corpora/school/) / [World](https://md.mova.elamur.ai/free/en/corpora/school/world/) / Solids, liquids and gases # Solids, liquids and gases Lesson 11 of the world course of Mova's primary school: 16 sentences, each with its syntax tree and pragmatics.

How Mova does on its tests: [the lesson at school](https://md.mova.elamur.ai/free/en/school-run/world/11-solids-liquids-gases/). - [0](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/0/) — Everything around us is made of matter: anything that has mass and takes up space, even the air. - [1](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/1/) — Matter is made of tiny particles, far too small to see, and they are always moving. - [2](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/2/) — In a solid the particles are packed tightly and only jiggle in place, so a solid keeps its own shape. - [3](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/3/) — In a liquid the particles are close together but slide past each other, so a liquid flows and takes the shape of its container, but keeps its volume. - [4](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/4/) — In a gas the particles are far apart and fly about fast, so a gas spreads out to fill any container it is in. - [5](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/5/) — For example, the same water can be a hard ice cube, a liquid in a glass, or invisible water vapour in the air. - [6](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/6/) — A solid has a fixed shape and a fixed volume. - [7](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/7/) — A liquid has a fixed volume but takes the shape of its container. - [8](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/8/) — A gas has no fixed shape or volume; it spreads out to fill its container. - [9](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/9/) — Gases can be squashed into a smaller space much more easily than solids or liquids. - [10](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/10/) — Air is a gas; it has mass and takes up space even though we cannot see it. - [11](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/11/) — Water vapour is water as a gas, and it is invisible. - [12](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/12/) — A smell is made of tiny particles of gas that spread out through the air until some reach your nose. - [13](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/13/) — Sand and sugar can be poured, but each grain is a tiny solid with its own shape. - [14](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/14/) — The particles of a gas are much farther apart than those of a solid or a liquid. - [15](https://md.mova.elamur.ai/free/en/corpora/school/world/11-solids-liquids-gases/15/) — Heating makes particles move faster; cooling makes them move more slowly. - ← previous: [Thinking like an astronomer](https://md.mova.elamur.ai/free/en/corpora/school/world/10-reasoning-about-space/) - next →: [Melting, freezing and boiling](https://md.mova.elamur.ai/free/en/corpora/school/world/12-melting-freezing-boiling/) - ↑ back to [World](https://md.mova.elamur.ai/free/en/corpora/school/world/)
