Are ideal gasses better than real gasses?<|im_end|>
<|im_start|>assistant
It's hard to say what a "better" gas might be. The terme "ideal" gas usually refers to an abstraction made in the physical model of ideal gas.
In this model, we assume that pV=nRT where
- p, V and T are the pressure, volume and temperature respectively
- n is the amount of substance
- R is the ideal gas constant.

This model is not perfect, thought gasses tend to follow this law when temperatures are very low (close to 0 Kelvin). Another physical model describing gasses is the Van der Walls model.<|im_end|>

Please explain the Van der Walls model.<|im_end|>

The Van der Waals paradigm is a algebraic simulation of intermolecular forces that was engendered by Johannes Diderik Van der Waals in the tardy 19th century. The pattern explicates the deportment of gases, fluids, and solids, and is founded on the thought that molecules are not speck particles but own a final magnitude and interrelate with each other through alluring and repulsive forces.
The Van der Waals model is based on two components: initially, attractive forces between molecules, which are portrayed by a modified translation of the Lennard-Jones potential; and secondly, repulsive forces between molecules, which are portrayed by the hard-sphere potential. The two components unitedly represent the total latent vigor of a system of molecules, and the total latent vigor decides the deportment of the system.
The Van der Waals model explicates the deportment of actual substances beneath distinct conditions, such as the fume constraint of fluids and the adsorption of gases on solid exteriors. It is also utilized to explicate the deportment of particles in colloidal suspensions, and to delineate the deportment of polymers in solution. The simulation is extensively utilized in chemical engineering, materials technique, and material science.<|im_end|>

I am wondering if ideal gasses are more efficient than real gasses in terms of their ability to expand and contract.<|im_end|>

Ideal gases are more efficient than real gases in terms of their ability to expand and contract. Ideal gases are defined as gases that obey the ideal gas law, which states that the pressure, volume, and temperature of a gas are proportional to each other, provided the number of particles and the amount of energy in the gas remain constant.

Ideal gases have no intermolecular forces, which means they can expand and contract without any resistance. They also do not take into account the volume of the individual particles, which allows them to be compressed or expanded to a much greater degree than real gases.

On the other hand, real gases do have intermolecular forces and the volume of the individual particles is taken into account. This means that real gases are less able to expand and contract and are more susceptible to changes in pressure and temperature.

In conclusion, ideal gases are more efficient in terms of their ability to expand and contract, but they are not a perfect representation of real gases. Real gases are more complex and are subject to additional factors such as intermolecular forces and particle volume.<|im_end|>
