Answers
Answer:
A gas completely fills the vessel in which it is kept because there is a 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
Answer:
A. because there is negligible force of attraction between the particles of gas.Due to this the particles moves freely in all the directions.
B. The molecules are colliding and when they collide with the wall they exerts a little force on the wall.
C. YES because solids are rigid , incompressible,have definite shape and volume,etc.
D. Particles of air have large space between them.While particles of block of wood do not have much space between them.
