Assumption of kinetic theory of gas?
The volume occupied by gas molecules is negligible when compared to volume occupied by the gas.The collisions between gas molecules-gas molecules and gas molecules-walls of the container are perfectly elastic.
Why is there no gas pressure inside a vacuum?
Gas pressure is caused by the molecules of gas striking the walls of a container, or in the case of Earth's atmosphere, the molecules of air hitting the earth. In a vacuum, there are no gas molecules. No molecules, no pressure.
Does nitrogen gas consist of atoms or molecules?
Nitrogen gas consists of N2 molecules.
A real gas differs from an ideal gas because the molecules of real gas have?
The molecules of real gas have some volume and some attraction for each other.
Explain what is the difference between real gas molecules and ideal gas molecules by kinetic theory?
In an ideal gas, molecules don't take up space, and don't have long-range interactions.

What can a gas be?
a gas can be molecules
Why is there no gas pressure inside a vacuum?
Gas pressure is caused by the molecules of gas striking the walls of a container, or in the case of Earth's atmosphere, the molecules of air hitting the earth. In a vacuum, there are no gas molecules. No molecules, no pressure.
Where is most of the gas molecules in the atmosphere found?
The atmosphere is made of gas molecules.
Why does a gas expand quickest?
Gas expands the quickest because gas molecules are farther apart than molecules of other substances. Gas molecules also move faster.
What is true if a liquid and a gas are in equilibrium?
liquid molecules forming a gas and gas molecule forming a liquid are equal in number
Does nitrogen gas consist of atoms or molecules?
Nitrogen gas consists of N2 molecules.
Gas molecules are far apart in the layer?
Gas molecules are far apart in which layer
What fraction of the average kinetic energy of hydrogen gas at 100K does hydrogen gas have at 40K?
40% -- it is directly proportional to the energy (in Kelvin)
When a gas is compressed in a cylinder what does the distance between the gas molecules do?
The compression will result in a lowering in the average distance between molecules of the gas. Imagine that the cylinder is like that in an internal combustion engine, with a piston inside the cylinder. The compression is accomplished by pressing the gas into a reduced volume. The number of gas molecules remains the same. With the same number of molecules in a reduced volume, the gas molecules are pressed more closely together, lowering the average distance between the gas molecules.
How does the speed of molecules of gas change when heated?
The speed of the molecules speeds up when the gas is heated.
Does a gas with large molecules has friction between its molecules?
A gas with large molecules has friction between its molecules because they are constantly coming into contact with each other. This is a normal process which does not alter the overall composition or characterises of the gas.
