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 results from the collision of gas molecules with the walls of their container. In a vacuum, there are very few or no gas molecules present to create this pressure through collisions, hence the absence of gas pressure inside a vacuum.
Does nitrogen gas consist of atoms or molecules?
Nitrogen gas consists of N2 molecules.
The molecules of gas are kept in the lower layers of the atmosphere by the force of?
gravity. Gravity pulls the gas molecules towards the Earth, keeping them in the lower layers of the atmosphere. If not for gravity, the gas molecules would disperse into space.
Which state has molecules in very loosely pack?
The state that has molecules packed very loosely is the gas state. In the gas state, molecules are not confined to a specific shape or volume and move freely in all directions.
What fraction of the average kinetic energy of hydrogen gas at 100K does hydrogen gas have at 40K?
The average kinetic energy of gas is directly proportional to the temperature. So at 40K, the fraction of the average kinetic energy of hydrogen gas compared to that at 100K would be (40K)/(100K) = 0.4 or 40%.

What can a gas be?
a gas can be molecules
Where is most of the gas molecules in the atmosphere found?
The atmosphere is made of gas molecules.

Does nitrogen gas consist of atoms or molecules?
Nitrogen gas consists of N2 molecules.
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.
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.
How ionisation occurs in gas molecules?
Ionization occurs in gas molecules, either by heating the gas to a high enough temperature, or by applying a high enough voltage through the gas, so that the gas molecules lose electrons, causing the gas to be ionized, at which point it is a plasma.
What happens to the number of molecules of the gas when it is compressed?
When a gas is compressed, the volume it occupies decreases, causing the gas molecules to be closer together. The number of molecules remains the same, as no molecules are added or removed during compression.
Is it true the molecules of a gas are much farther apart than molecules in a liquid?
Yes. The molecules of a gas spread out to fill their entire container.
How many water molecules (H2O) can be produced from 6 molecules of hydrogen gas (purple) reacting with 6 molecules of oxygen gas (turquoise)?
6 molecules of hydrogen gas reacting with 6 molecules of oxygen gas will produce 6 molecules of water.
