If the particles in a sample of matter have an orderly arrangement and move only in place, the sample is a

Hi!

The answer would be solid.

Explanation:

There are three essential states of matter:

In a solid, the particles are seen to be in a strict orderly arrangement, and only show restricted movement about their place.

In a liquid, the particles do not have a particular arrangement, and have a more free movement with respect to solid, and can change their position through the sample.

In a gas, the particles are most widely spaced, and have no defined arrangement. They have the most free movement of the other two states.
