Question

Q4) Give reason- “A gas fills a vessel completely in which it is kept”..​

Answer 1

Answer:

as it has no definite volume and fills container completely

Answer 2

Answer:

A gas completely fills the vessel in which it is kept because there is negligible force of attraction between the particles of gas. Thus, the gas particles move freely in all directions. ... These collisions of the gas particles with the walls of the container exert pressure on the walls of the container.
