Air is about 78.0 percent nitrogen molecules and 21.0 percent oxygen molecules Several other gases make up the remaining 1 percent of air moleculesWhat is the partial pressure of nitrogen in air at at?
0.780 Atm
Why is Air made from molecules?
A molecule is any two combined atoms. The two principal gases in the air are nitrogen and oxygen . Nitrogen gas is a molecule of two nitrogen atoms triply bonded together and represented by N2 , ( N///N) Oxygen gas is molecule of two oxygen atoms doubly bonded together and represented by O2 (O=O). Other molecules in the air are , Carbon Dioxide (CO2(O=C=O)) , water (H2O(H-O-H)) . Also Nitrogewn oxides, sulphur dioxide, hydrogen sulphide, methane. They are all molecules because they are two or more atoms bonded together. However, there are the Noble(Inert) gases, which are NOT molecules, because they exist as single (uncombined) atoms, referred to as 'monatomic gases'. These gases are , Helium, Neon, Argon, Krypton, The air is a mixture of these gases. In the mix there is ;- 78% nitrogen (N2) 21% oxygen (O2) The remaining 1% consists of all the other gases. Mankind may be very worried about the carbon dioxide level in the air, but its concentration is actually very low!!!!!( much less than 1%).
Is gas polar?
Some gases have polar molecules as HCl, HBr, SO2, but not all gases have polar molecules.
What kind of molecules are in gases?
All OH3
The properties of solid liquid and gases?
Solid molecules are rigid and has a shape. Liquid molecules are less rigid than solid and the molecules move. Gases have no shape and its molecules are free floating and move at rapid speeds against each other.
Why can only solids vibrate but liquid and gases can't?
Liquids and gases can vibrate. In fact sound is the vibration of air molecules.
Explain why air has pressure?
The simplest explanation is that air is composed of gases. Gases are composed of molecules. Molecules have mass. The closer molecules get to the center and bottom of the gravity well, the more closely packed they become, because successive "layers" pack down on those below, piling up. The weight of the gases on top of those on the bottom compress those on the bottom.
What is made of gas?
Gases are made up of high energy molecules and atoms.
Why it is easier to compress air as compare to water?
Air and other gases have spaces between the molecules, which are constantly flying around and colliding with each other and bouncing apart. In liquids, the molecules are close together, touching each other. This is why gases are compressable and liquids are not.

0.780 Atm
What is air motion rate?
Bulk air motion is called "wind speed". Motion of individual molecules in air is covered by temperature and the "kinetic theory of gases".
When molecules in liquids and gases are heated they?
When molecules in liquids and gases are heated they move faster
Does atoms and molecules of gases and liquids are heated they sink?
after atoms and molecules of gases and liquids are heated, they sink?
What happens when air is compressed?
When air particles are compressed, the density is increased. There is more pressure within a region or within a container. There are more molecules in a given volume, and this can cause the air to heat up. - The pressure of the air increases, as does its temperature, as its volume decreases.

What do you know about gases molecules?
Molecules of a gas are in permanent motion.
What are gases in nature are molecules?
All gasses that are not noble gases (well xenon and heaviei forms some interesting "patterns", if not truly molecules), or plasmas, are molecular gases.
