Why can ideal gas technically not exist in the real world give 2 reasons?

The gas particles would need to occupy zero volume and they would need to exhibit no attractive forces what so ever toward each other. Since neither of those conditions can be true, there is no such thing as an ideal gas.

Can an ideal gas actually exist Why or why not?

While no ideal gases exist, many gases behave like ideal gases under certain conditions….Nomenclature.

Ek	=	kinetic energy, J
R	=	gas-law constant, J/(g mol-K)
T	=	absolute temperature, K
v	=	velocity, m/s
V	=	volume, m3

Why is the ideal gas law useful even though ideal gases technically do not exist?

Explanation: Of course, an ideal gas does not exist except as a conceptual notion, an ideal. Under conditions of low pressure and high temperature, all gases behave like real gases, even gases such as UF6 . Idealization is therefore useful.

What are the conditions for ideal gas equation?

The ideal gas law assumes that gases behave ideally, meaning they adhere to the following characteristics: (1) the collisions occurring between molecules are elastic and their motion is frictionless, meaning that the molecules do not lose energy; (2) the total volume of the individual molecules is magnitudes smaller …

What is true for ideal gases but not always true for real gases?

Ideal gases are hypothetical gases where their molecules occupy negligible space and have no interactions with other particles. Real gases have non-negligible excluded volume (volume between them). Ideal gases do not. When in collision with other gas particles, energy is “lost” in real gases.

Why an ideal system does not exist?

The ideal gas model tends to fail at lower temperatures or higher pressures, when intermolecular forces and molecular size becomes important. It also fails for most heavy gases, such as many refrigerants, and for gases with strong intermolecular forces, notably water vapor.

How are real gases different from ideal gases real gases differ from ideal gases because in a real gas?

Hence, intuitively deducing, real gases differ from ideal gases in the sense that: Real gas molecules possess potential energy, i.e. they are affected by intermolecular forces. The volume of real gas molecules is NOT negligible. The real gas molecules are not spherical in shape.

What assumptions does the kinetic theory make about ideal gases that are not true of real gases?

The simplest kinetic model is based on the assumptions that: (1) the gas is composed of a large number of identical molecules moving in random directions, separated by distances that are large compared with their size; (2) the molecules undergo perfectly elastic collisions (no energy loss) with each other and with the …
