If the molecules of a substanace spread out compltely to fill the entire shape of any container the substance is placed in , the substance is probly a

Gas.

Explanation:

Matter can be found in nature in three states: solid, liquid, and gas. The main difference between these three states is the separation of its molecules.

A solid has a definite form, its molecules are closely packed together and there is little to no movement between each molecule. When put in a container, it retains its form.

A liquid does not have a definite form, its molecules can move past another and they are not as close as in a solid, but it is not as loose either. When put in a container, it takes the shape of the container but it has a defined surface.

A gas does not have a definite form, its molecules are totally free from one another and the distance that separates them is much larger than the size they have. When placed in a container, they spread out completely and fill the entire shape of the container.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
