A) Oscillate

B) Liquid

C) Loosely

That is, "They can oscillate about a fixed point. Particles in a liquid are still close together but are arranged loosely (not in a pattern)

Explanation:

The above speaks to the various states that matter can be in. They are Gaseous, Liquid, and Solid.

The state described above is the liquid state. Recall that all matter are made up of microscopic particles. These particles when viewed under a microscope are observed to be in a state of continuous motion.

The degree of motion and arrangement is determined by the temprature of the substance. The higher the temperature, the faster and more lose the particles become.

Water for instance would in a liquid state, have its particles oscillate freely about each other giving it the ability to take the shape of the container in which it is put. Its particles are not rigidly fixed together at this point and can slide past each other easily.

In a solid-state (that is ice) the particles become tightly packed and there is less oscillation. Whilst in a gaseous state (vapor, that is) the particles o or molecules are very far apart.
