Answer:
2: Liquid
Explanation:
Liquid has no shape (think of pouring water from a bowl to a cube, it doesn't keep the same shape) but has the same volume (from bowl to cube is still the same volume)
Hope this helps, have a nice day :))
There are some people disagreeing with me, so here are the others:
<em>(which is totally okay, just wanted to clear it up!)</em>
Solid: Has a definite shape and a definite volume (<em>a cube will stay a cube</em>)
Liquid: Has no shape, but definite volume (<em>will change shapes but has same volume</em>) <u>(answer)</u>
Gas: No shape, no volume (<em>will change shapes, but also does not have a set volume</em>)
Plasma: No shape, no volume (<em>ionized gas</em>)
