Answer:
Gas
Explanation:
There are three states of matter.
Solid, liquid and gas
Solid: it is the state of matter in which shape and size both are fixed. The interatomic forces are very large. For example, stone, plastic, etc.
Liquid: it is the state of matter in which volume is fixed but can attain the shape of container in which it is kept. The interatomic forces are lesser in magnitude as compared to solids. For example, water, milk, etc.
Gas: it is the state of matter in which both shape and size are not fixed. The interatomic forces are very less as compared to solids or liquids. For example, hydrogen, oxygen, etc.
