Question

Differentiate between ideal gas and real gas.

Answer 1

Hint: Gas: Gas is one of the four fundamental states of matters. It neither has any independent shape nor volume. They are free to expand infinitely. Gas is tasteless, odorless. Gas has indefinite shape and volume. Gas can be compressible as well as expendable. As we know that the equation of ideal gas is:
 $ \Rightarrow pV = nRT$

Complete step by step solution:
Ideal Gas: An ideal gas is defined as the gas that obey gas laws at all conditions of pressure and temperature. Ideal as it has velocity and mass but it doesn’t have any volume. When it compares the total volume occupied is negligible. It does not have any condense point or triple point.
Real Gas: Real gas is defined as the gas that does not obey gas law at any condition. When gas becomes massive and has more volume it deviates from its real behavior. Real gas has velocity, mass and volume. It has a triple point and a condensed point. Its volume is not negligible.

S.N	Ideal Gas	Real Gas
1	No definite volume	Having volume
2	Elastic collision of particles	Non-elastic collision of particle
3	It is hypothetical	It exist in real
4	No intermolecular attraction force is occurred	Having intermolecular attraction force.
5	It is independent gas	It interacts with others.
6	It has high pressure	It has low pressure as compared to high pressure.

Note: Gas laws are used to explain the mechanics where pressure, temperature and volume are affected. It is independent and non-intermolecular interaction with others. They deal with all the four quantities. Ideal gas follows the all criteria of Charles’s law, Boyle’s Law and Avogadro’s law.
