Difference between Gas and Ideal Gas

Gas and ideal gas are both states of matter, but there are some key differences between them. Let's explore these differences in more detail:

1. Definition: - Gas: Gas is a state of matter in which the particles are in constant motion and have enough kinetic energy to overcome the attractive forces between them. Gases can expand to fill the container they are in and have no definite shape or volume. - Ideal Gas: An ideal gas is a theoretical concept used to simplify the study of gases. It assumes that gas particles have no volume and do not interact with each other. Ideal gases follow certain gas laws, such as Boyle's law, Charles's law, and Avogadro's law, under specific conditions.

2. Particle Interactions: - Gas: In a gas, the particles interact with each other through intermolecular forces, such as van der Waals forces. These forces can cause the gas particles to attract or repel each other, leading to deviations from ideal gas behavior. - Ideal Gas: In an ideal gas, the particles do not interact with each other. They are assumed to have no volume and do not experience any intermolecular forces. This assumption simplifies the calculations and allows for the application of gas laws.

3. Volume and Shape: - Gas: Gases have no definite shape or volume. They can expand to fill the container they are in and can be compressed under high pressure. - Ideal Gas: Ideal gases are assumed to have no volume. They occupy the entire volume of the container they are in and can be compressed to any extent without any change in their properties.

4. Behavior under Different Conditions: - Gas: Real gases exhibit non-ideal behavior under certain conditions, such as at high pressures or low temperatures. At these conditions, the intermolecular forces become significant, and the gas deviates from ideal gas behavior. - Ideal Gas: Ideal gases follow the ideal gas law, which states that the pressure, volume, and temperature of an ideal gas are related by the equation PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature. Ideal gases obey this equation under all conditions.

In summary, the main difference between gas and ideal gas lies in their assumptions and behavior. While gas is a general term for the state of matter, ideal gas is a theoretical concept that assumes no particle interactions and no volume for the gas particles. Ideal gases follow specific gas laws, while real gases may deviate from ideal behavior under certain conditions.
