Is the form of matter that has no shape and a definite volume.
1: plasma
2:liquid
3:solid
4:gas

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)

(which is totally okay, just wanted to clear it up!)

Solid: Has a definite shape and a definite volume (a cube will stay a cube)

Liquid: Has no shape, but definite volume (will change shapes but has same volume) (answer)

Gas: No shape, no volume (will change shapes, but also does not have a set volume)

Plasma: No shape, no volume (ionized gas)
