Liquids are one of the three states of matter. And the two key properties of liquids for you to remember are they have a fixed volume and weight, just like solids, but they change their shape to fit their container which is unlike solids. Now, the first thing you think of when you think liquid is water. If I asked you what shape is water, you wouldn't be able to answer because liquids do not have a definite shape. Liquids take the shape of the container they're in. So, liquid can be poured from one container to another, and it will form the shape of its new container. Now, although liquids will change shape when moved between different containers, the volume will stay the same. So, however you move it, when you measure it, it stays the same. In liquids, the particles are near each other, but they're not tightly packed like solids. The particles in liquid are able to just slide past each other and this allows for the movement of particles throughout the liquid. The looser the arrangement of particles is what allows the liquids to take the shape of their container. Some more examples of liquids might be juice or milk. And what other ones can you think of? Liquids have a fixed weight and volume but they change their shape to fit their container.
