Ideal Real
Made of small particles that
have MASS
SAME
Gases are mostly empty space SAME
Low density SAME
Gas particle are in constant
random straight line motion
SAME
There are NO attractive or
repulsive forces between
particles
There are VERY SMALL
attractive and repulsive forces
between particles
Particles have NO volume Particles have a very small
volume.
Collisions are ELASTIC
(no loss in total kinetic energy)
Collisions are inelastic (NOT
Elastic) (When gas particles
collide they will lose energy.)
