1.	Give the reason (A) the gas fills completely the vessel in which it is kept. (B) a gas exert pressure on the walls on the container (C) a wooden table should be called a solid (D) we can easily move our hand in air but to do the same through a solid block of wood we need a karate expert.
Answer» e is little attraction between particles of gas . Thus , gas particles move FREELY in all directions . therefore , gas COMPLETELY FILLS the vessel in which it is kept b) Particles of gas move randomly in all directions at high speed .As a result .the particles hit each other and also hit the walls of the CONTAINER with a force . therefore ,gas exerts pressure on the walls of the container .c) A wooden table has a definite SHAPE and volume . It is very rigid and cannot be compressed i.e . it has the characteristics of a solid .hence a wooden table should be called a solid .d) Particles of air have large space between them on the other hand , wood has little space between its particles .Also ,it is rigid . for this reason . we can easily move our hands in air , but to do the same through a solid block of wood ,we need karate expert .
