Question

What are the characteristics of an ideal gas?

Answer 1

Ideal Gases: -

1. Particles in gases move randomly and continuously. They keep moving straight ahead until they run against something, generally another particle or the container walls.
2. The molecules' collisions with the container walls result in gas pressure. Collisions don't result in any energy gain or loss.
3. At all temperatures and pressures, an ideal gas follows the equation PV = nRT. In contrast to real gases, which have tiny volumes, ideal gases have no volume.
4. An Ideal gas's Kelvin temperature can be calculated from its kinetic energy. The average of the individual gas molecules' speeds is used to determine the gas's temperature and kinetic energy. The average kinetic energy of all gases is the same for a given temperature.
5. An Ideal gas particle's average kinetic energy is inversely related to temperature. The speed of the gas molecules increases as the temperature rises.

Characteristics of Ideal Gases: -

1. Numerous identical molecules make up an ideal gas. In many aspects, an ideal gas differs from a real gas.
2. When compared to the volume occupied by the gas, the volume that the molecules themselves occupy is insignificant.
3. The molecules move randomly while adhering to Newton's equations of motion.
4. Only when molecules collide do they sense forces; all other collisions are totally elastic and take very little time.
5. The average kinetic energy of all gases is the same for a given temperature.
6. Gas molecules that are lighter than heavier ones move more quickly.
7. Since an ideal gas is referred to as a particle because particles don't have any mass, the ideal gas's mass can be ignored in the calculation because it doesn't exist.
