Ideal gas and nobal gas

What is an ideal gas?

An ideal gas is one that abides by the gas laws under all possible pressure and temperature conditions. The gas must adhere to the kinetic-molecular theory in its entirety to achieve this. The gas particles must have no volume and must not interact with one another in any way that could be considered attractive. There is no such thing as an ideal gas because neither of those statements can be true. 

If there is no ideal gas, then what is normal gas known as?

Gas that exists in the real world are known as “Real Gas”. The term real gas usually refers to a gas does not behave like an ideal gas. Their behaviour can be explained by the interactions between the gaseous molecules. These intermolecular interactions between the gas particles is the reason why real gases do not adhere to the ideal gas law. Therefore, “Real gases can be defined as non-ideal gases whose molecules occupy a given amount of space and have the ability to interact with each other”.

What governs ideal gas behivour?

The ideal gas law governs the behivour of the ideal gas and this relationship between pressure, volume, temperature, and the total number of molecules in a gas sample is expressed mathematically by  PV = nRT, where n is the number of moles of gas, P is pressure, V is volume, R is the ideal gas constant, and T is temperature.

Then what about Real gas?

Real gases have volume, and their molecules do interact with each other. This means that the behavior of real gases is more complex than that of ideal gases. One way to account for the real gas behavior is to use the van der Waals equation. The van der Waals equation is a modification of the ideal gas law that takes into account the volume and attractive forces between gas molecules. This equation allows us to better predict the behavior of real gases.

Conclusion

In summary, ideal gases are a theoretical concept that assume no volume or interaction between gas molecules. Real gases, on the other hand, have volume and interact with each other. The behavior of real gases is more complex, and we can describe it using the van der Waals equation.
