What best describes the molecules of an ideal gas?
Molecules of an ideal gas are considered to be point masses that do not have any volume, do not interact with each other, and collide with each other and the container walls in perfectly elastic collisions. The behavior of ideal gases is described by the ideal gas law, which relates pressure, volume, and temperature.
Are there forces of attraction between the particles in a gas?
In a gas, the particles are typically moving at high speeds and are far apart, so the forces of attraction between them are negligible. Interactions between gas particles are more controlled by collisions than by attractive forces.
Would a gas whose molecules were true geometric points obey the ideal gas law?
If gas molecules were true geometric points (ie had zero volume) AND had zero intermolecular interaction (such as attraction or repulsion), then the gas would obey the ideal gas law. Gases composed of small, non-interactive molecules (such as helium gas) obey the ideal gas law pretty well (as long as the gas is low density and temperature is rather high). For non-ideal gases, at least two correction factors are often used to modify the ideal gas law (correcting for non-zero volume of gas molecule and intermolecular attraction) such as in the Van der Waals equation for a real gas.
What characteristic would make a gas non ideal?
The gas molecules interact with one another
Is ideal gas one whose particles take up space?
An ideal gas is a theoritical gas consisting of randomly moving particles.The kinetic theory of ideal gases makes 5 main assumptions:The size of molecules is negligible compared with the mean intermolecular distance (i.e. they are widely spaced molecules).Molecules move with different speeds and in random directions.Standard laws of motion apply.Collisions between molecules are elastic. Translational kinetic energy is not converted into other forms of energy.There are no attractive intermolecular forces between molecules except during collision.

Which gas of the following will have the greatest deviation from ideal behavior H2 F2 Br2 and Cl2?
The two factor Van de Waals gave as correction for real molecules instead of the ideal gas, are the size of the molecule, and the amount of attraction between the molecules. The larger the size of the molecule for the greater the deviation from an ideal gas, clearly bromine wins here since it has the biggest size of its atom. The amount of attraction between molecules is directly proportional to the boiling point of the liquid made from those molecules, and again bromine wins here since its has the highest boiling point. So bromine has the greatest deviation from ideal gas behaviour.
Diff between real gas and ideal gas?
In an ideal gas molecules interact only elastically.
Are there forces of attraction between the particles in a gas?
In a gas, the particles are typically moving at high speeds and are far apart, so the forces of attraction between them are negligible. Interactions between gas particles are more controlled by collisions than by attractive forces.
What happenes to the particels of a gas when there are fewer of them?
This is the ideal gas with no collisions between molecules..
What are two characteristics of an ideal gas that are not true of a real gas?
they have no volume and their molecular force of attraction is negligible

What aspects are not accounted for in the ideal gas law?
The ideal gas law does not account for the volume occupied by gas particles and the interactions between gas molecules.
What are real and ideal gases and are all real gases ideal?
Ideal gases can be explained by the Kinetic Molecular Theory: 1) no attraction between gas particles 2) volume of individual gas particles are essentially zero 3) occupy all space available 4) random motion 5) the average kinetic energy is directly proportional to Kelvin Real gases has volume and attraction exists between gas particles. No gas behaves entirely ideal. Real gases act most ideal when temperature is is high and at low pressure.
What force causes a difference between the ideal and the mechanical advantage Of the same object?
The force required to overcome friction between parts of a machine or device causes a difference between the ideal and mechanical advantage of the object. Friction reduces the efficiency of a machine by causing energy losses, making it harder to achieve the theoretical ideal advantage.
What characteristic would make a gas non ideal?
The gas molecules interact with one another
What is the difference between real gas molecules and ideal gas molecules?
Ideal gases are assuming that gas particles are discrete point particles, thus bouncing off each other with no attraction with one another, and each molecule taking up no space. This assumption allows for the Ideal gas law, which states exact proportions between measurable quantities in gases: pressure, volume, temperature, number of particles.The ideal gas law is: PV = nRTwhere:P is pressureV is volumen is number of moles of gasR is ideal gas constantT is temperature (K)Real gases particles, as common sense suggest, dohave volume and are minutely attracted to each other. Thus, gases do deviate from ideal behavior especially as they get more massive and voluminous. Thus, the attractions between the particles and the volume taken up by the particles must be taken into account. The equation derived by Van der Waals is the Van der Waals equation which simulates real gas behavior.The Van der Waals equation is:(p + ((n2a)/V2)(V - nb) = nRTwhere:p is measured pressure of the gasn is number of moles of gasa is attraction constant of the gas, varies from gas to gasV is measured volume of the gasb is volume constant of the gas, also varies from gas to gasR is ideal gas constantT is temperature (K)Basically the Van der Waals equation is compensating for the non ideal attraction and volume of the gas. It is similar to PV = nRT, identical on the right side. To compensate for the massless volume that is found in ideal equation, the volume of the molecules are subtracted from the observed. Since, the equation of gas behavior concentrates on the space between the gas particles, and the volume of gas adds to the measured amount that should be used in the equation, thus it is subtracted from the equation. Another compensation is the fact that attraction between particles reduces the force on the walls of the container thus the pressure, thus it must be added back into the equation, thus the addition of the a term.
