Processes Involved in Preparing an Ideal Gas

Before we proceed toward the complex topics and terms, let’s discuss the basics. In the first set of questions, let’s answer what an ideal gas is? An ideal gas particle has no volume or mass. The Ideal Gas Law governs it. Some characteristics of the ideal gas that will help you understand it better are: it has very low attractive intermolecular forces between the particles. It means more elasticity for the particles to move about freely in open space. It is also said that the ideal gas particle  had no volume, mass, or even velocity. Nothing is specified for the ideal gas. Due to this, there is no effect of any of the components on the ideal gas. There is a lot of elasticity for the free particles. 

 Although the ideal gases are hypothetical, they still have some dependency on absolute temperature, absolute pressure, and volume. All these five components together form the equation for the Ideal Gas Law. All these components are also interdependent pendant associations. 

What is an ideal gas?

Any gas that adheres to the Ideal Gas Law and has no mass, volume, or velocity is termed an ideal gas. An ideal gas is defined as a gas that lacks any intermolecular forces of attraction. It also has no volume of its own. Let’s assume that spherical balls are present nearby the tone or a container. However, they do not have any contact as such with each other. They may collide with each other but are still contactless. The particles of the ideal gas have the liberty to move freely. They are elastic and have no boundaries of their own.  

The other characteristics of the ideal gas that makes it different from a real gas are: 

• It only possesses Kinetic Energy and does not have any potential energy.
• The volume of an ideal gas is always zero.
• The pressure of the ideal gas is high as compared to real gas.
• There are absolutely no attractive and repulsive forces present in an ideal gas. 
• Elasticity is evident in the ideal gas molecules.
• They have no designated mass.
• There is no designated volume.
• It is hypothetical and has no real-life examples.
• Some gases may behave as ideal under critical conditions.

What are the components of an ideal gas? 

To determine the various components of an ideal gas, we need to explore the Ideal Gas Law first. 

The Ideal Gas Law states that certain components have a strong connection with that of an ideal gas. These are: 

• P: Absolutely Pressure 
• T: Absolute Temperature
• V: Volume 

However, there is an overall increase in the temperature of the particles when a change occurs in the kinetic energy of the particles of the gas. This states that all the three components mentioned above have an interdependency on each other. 

When we derive a relationship between them, it is as follows: 

Ideal Gas Law: PV = NRT = NkT 

Herein, R = Universal Gas Constant = 8.3145 J/mol K

• n = number of moles 
• k = Boltzmann Constant 1.38066 x 10-23 J/K = 8.617385 x 10-5 eV/K
• k = R/NA
• NA = Avagadro’s Number = 6.0221 x 1023 /mol
•  N = number of molecules

Hence, the various components of an ideal gas are temperature, pressure, number of moles, the universal gas constant, and volume. 

What is the preparation of ideal gas? 

There is no ideal preparation of ideal gas. It can only be derived by the various equations of the Ideal Gas Law.

As mentioned above, we discussed the molecular form of the Ideal Gas Law. However, if we were to determine the molecular form of the Ideal Gas Law, it would be completely different.

Herein, N: Number of molecules instead of n: number of moles. 

If we were to derive the Ideal Gas Law now, 

It would be: 

PV= Nkb T

Where P = Pressure of Gas 

V = Volume of Gas

N = Number of Molecules

T= Temperature of the Gas 

kb = Boltzmann Constant = 1.38×10-23 J/K 

The units would be:

Pressure in Pascal 

Temperature in Kelvin 

Volume in metre cube 

Conclusion 

In this article, we walked you through the definition of an ideal gas and answered the question: what is an ideal gas? An ideal gas always obeys the Ideal Gas Law. It lacks any volume or mass of its own. It only possesses Kinetic Energy and does not have any potential energy. The volume of an ideal gas is always zero. The intermolecular forces of attraction in the ideal gas are negligible or absent too. This means that the particles have the absolute freedom to move around without hassles. This, in turn, also confirms that there is a presence of elasticity in the ideal gas. Moreover, It is hypothetical and has no real-life examples. Some gases may behave as ideal under critical conditions. 

The Ideal Gas Law states that any change in the overall temperature of the gas also causes a change in the internal temperature of the ideal gas. This, in turn, causes a change in kinetic energy as a change follows this in temperature. The interdependency of all these components on each other yields the results of the Ideal Gas Law equation. The equation can be seen in both molars as well as molecular forms. Both of them contribute to the preparation of ideal gas.
