give me the detail ,please!

Because gas particles consist of molecules,the distance between molecules are relatively large compared to liquid and solid.The molecules move in rapid,random and straight-line motion,they move in all diections,and they collide with each other and the walls of the container.Attraction and repulsion is negligible in gas particles.Therefore they fill the container.
应该用统计的观点来解释。实际上，气体分子充满容器的情况出现的概率最大。
嗯，应该是热力学第二定律决定的，物质总是朝着无序度最高的方向发展
事实上，不是充满，存在着间隙。
所谓的充满不过是容器的每个角落都会被气体“光顾”而已。
Because the gas is liquid (or gas).
