Non-ideal gases deviate from the ideal gas law.

Unlike ideal gases, non-ideal gases do not completely follow the ideal gas law equation PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.

Intermolecular forces play a significant role.

Non-ideal gases experience intermolecular attractions or repulsions, which affect their behavior and deviate from the simple assumptions made in the ideal gas law.

Non-ideal gases can exhibit compressibility.

Unlike ideal gases, non-ideal gases can be compressed at high pressures due to the intermolecular forces between their particles.

Non-ideal gases may occupy larger volumes than predicted.

Under certain conditions, non-ideal gases occupy larger volumes than expected based on the ideal gas law. This is known as real gas volume.

Non-ideal gases can liquefy at lower temperatures.

Non-ideal gases have a greater tendency to condense and form liquids compared to ideal gases, especially at lower temperatures.

Non-ideal gases exhibit different behavior at high pressures.

At high pressures, non-ideal gases deviate significantly from ideal gas behavior due to the increased impact of intermolecular forces.

Non-ideal gases show variations in heat capacities.

Unlike ideal gases, non-ideal gases have heat capacities that depend on the conditions and intermolecular forces involved.

Non-ideal gases can undergo phase transitions.

Under specific temperature and pressure conditions, non-ideal gases can transition between gas, liquid, and solid states.

Non-ideal gases can exhibit hysteresis.

Hysteresis is observed in non-ideal gases, where the behavior of the gas during expansion is different from that during compression.

Non-ideal gases can form ideal gas mixtures.

While non-ideal gases have deviations from ideal gas behavior individually, when mixed together, they can exhibit ideal gas behavior as a mixture.

Non-ideal gases show variations in diffusion rates.

The diffusion rates of non-ideal gases depend on their molecular mass, temperature, pressure, and the presence of other gases in the mixture.

Non-ideal gases can experience condensation.

Under appropriate conditions, non-ideal gases can undergo condensation and transform into liquids or solids.

Non-ideal gases are extensively studied in real-world applications.

Understanding the behavior of non-ideal gases is crucial in fields such as chemical engineering, environmental science, and industrial processes, where gases are encountered in non-ideal conditions.

These 13 astounding facts about non-ideal gas showcase its complexity and the importance of studying its behavior beyond the ideal gas assumptions.
