gaseous state

the state of matter distinguished from the solid and liquid states by: relatively low density and viscosity; relatively great expansion and contraction with changes in pressure and temperature; the ability to diffuse readily; and the spontaneous tendency to become distributed uniformly throughout any container

固体および液体の状態とは異なる物質の状態であり、比較的低い密度と粘度、圧力と温度の変化に伴う比較的大きな膨張と収縮、容易に拡散する能力、およびあらゆる容器全体に自発的に均一に分布する傾向によって区別される
