Question

explain why a gas fills a vessel completely?​

Answer 1

Explanation:

(a) The particles of gases have low force of attraction between them. The particles are freely moving in the vessel in which it is filled.  

(b) The particles of gas has least force of attraction. They are constantly moving randomly. The particle of gas hit the walls of container thereby applying force and hence pressure on the wall.

(c) Wooden table has a definite shape and the definite volume. The particles of wood are closely packed. They do not take the shape of the container. Hence wooden table satisfies the properties of solid.

(d) The particles of air are very loosely bounded. They are far away from each other having a lot of space between them. Hence we can easily move our hands in air. But in a solid block, the particles are tightly held by a strong force of attraction. So there is some or no space between them. Hence we need a karate expert.

Answer 2

Heyaa user ! ☺

>> Here's your answer :

•A gas fills a vessel completely in which it is kept as there is negligible force of attraction between it's particles and also the intermolecular distance is very large.

•Thus gas particles are free to move in any direction and completely occupy all the space of the vessel they are kept in.
