Real gases exhibit attractive and repulsive intermolecular forces between particles, have volume, and undergo inelastic collisions where kinetic energy is lost. In contrast, ideal gases are modeled as having zero particle volume, no intermolecular forces, and perfectly elastic collisions where no kinetic energy is lost. While both real and ideal gases are composed of particles in random motion, real gases better model the behavior of gases under high pressure and low temperature conditions compared to ideal gases.

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

4. Real Gases
If enough pressure is applied, the gas will turn into a
liquid.
All particles have the same volume.
It allows laws under high pressure and low
temperature.
The collisions are not elastic.
They have polar intermolecular attractive forces.

5. Ideal Gases
They take up no space.
They are no intermolecular attractive forces.
Particles are moving in constant, random motion.
The collisions are elastic.
There is no attraction or repulsion with the container.
It allows laws under all conditions of temperature and
pressure.
