What does it mean for volume to be negligible?

When we say that the volume of the molecules is negligible, we mean that the total equilibrium volume of a gas is roughly the volume of free space the molecules have to move around.

Why is the actual volume of molecules of gas is negligible as compared to the total volume of gas?

gases consist of large numbers of molecules that are in continuous, random motion. 2. the combined volume of all the molecules of gas is negligible relative to the total volume in which the gas is contained. Attractive repulsive forces between gas molecules are negligible.

Is volume of molecule negligible?

The volume of a molecule is negligible when comparing with the distance between two molecules. 4. The volume of all the molecules of a gas is too much small when comparing with the container of that gas.

Why is the volume of a gas that of the container and not of the gas molecules?

The size of a gas particle is negligible as compares to the volume of the container in which the gas is placed. Gases are mostly empty space, and this is evident because gases can be easily compressed. It is easy to reduce the volume of a gas as compared to reducing the volume of a solid.

Why is the volume of an ideal gas considered to be negligible?

The Ideal Gas Law assumes several factors about the molecules of gas. The volume of the molecules is considered negligible compared to the volume of the container in which they are held. Attractive and repulsive forces between the molecules are therefore considered negligible.

What does non zero volume mean?

excluded volume
Real gases are made up of particles that occupy a non-zero volume known as the excluded volume. The van der Waals equation includes a volume-correction term that is specific to each gas; if a gas is behaving in an ideal manner, the correction term becomes negligible relative to the total volume.

Why is the volume of gas negligible?

The gas particles have negligible volume. The gas particles are equally sized and do not have intermolecular forces (attraction or repulsion) with other gas particles. The gas particles move randomly in agreement with Newton’s Laws of Motion. The gas particles have perfect elastic collisions with no energy loss.

Is the combined volume of all the molecules of the gas is negligible relative to the total volume in which the gas is contained?

Nothing is ever perfect, but close is good enough. The volume of all the molecules of the gas is negligible compared to the total volume in which the gas is contained (This is equivalent to stating that the average distance separating the gas particles is large compared to their size).

Which of the following is negligible in gas molecules?

In kinetic theory of gases, the volume occupied by the gas molecules is considered negligible in comparison to the volume of gas.

Does the volume of a gas change based on the container it’s in?

Avagadro’s Law- Gives the relationship between volume and amount of gas in moles when pressure and temperature are held constant. If the amount of gas in a container is increased, the volume increases. If the amount of gas in a container is decreased, the volume decreases.

Why is the real volume not the volume of the container?

At low pressures, the gaseous molecules are relatively far apart, but as the pressure of the gas increases, the intermolecular distances become smaller and smaller . As a result, the volume occupied by the molecules becomes significant compared with the volume of the container.
