This is a gas.
Gas
Gas, then liquid, and finally solid. Gases have the weakes intramolecular forces of attraction (the forces that hold molecules of a substance together), and therefore have the most freedom to move about.
The principle is based on equilibrium of the molecules between the mobile phase and the stationary phase. This will vary depending on the polarity of the substance, and the two phases. If the substance in more soluble in the mobile phase, it will travel further, and vice versa.
a phases change is when a substance goes from being a solid to liquid to gas. in solids the molecules have slowed down and are ridged. In liquids, molecules have free form movement and take the shape of their container. In gases, molecules have free form movement and move quickly, they take up all the space in their containers.

All three phases.

Solid: Molecules are tightly packed together into a fixed shape, so the molecules only have room to vibrate in place. ex: a classroom Liquid: Molecules have room to spread out and can slide past each other and takes the shape of the container it's in. ex: a hallway Gas: Molecules have room to go wherever and don't touch each other but still takes form of it's container. ex: outside; parking lot

A single substance has one phase.
