The basic tenets of Kinetic Molecular Theory (KMT)
as they relate to gases:
Particles of a gas:
a. are in constant motion, moving in straight lines
until they collide with another particle or a wall of the container in which they are enclosed.
b. experience elastic collisions; i.e.,
they do not eventually “run down”.
do not stick to other particles.
The speed of the particles is related to their temperature.
The pressure of a gas is related to the frequency and impact of the collisions of the gas particles with the sides
of the container in which they are enclosed.
