Gas particles have enough kinetic energy to overcome intermolecular forces that hold solids and liquids together, thus a gas has no definite volume and no definite shape.
(ROOT (S (NP (NNP Gas)) (VP (VBZ has) (NP (NP (DT no) (JJ definite) (NN volume)) (CC and) (NP (DT no) (JJ definite) (NN shape)))) (. .)))
Gas has no definite volume and no definite shape.
