Solids, Gasses, Liquids

Explanation:

Solids are rigid structures that have a definite share and volume.

Gasses will continue to spread indefinitely until pressure prevents further spreading.

Liquids have a volume but take the shape of the container they are in.  

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
