Air pressure becomes lower as water molecules are added to the air because water molecules .?

Water molecules displace some of the air molecules, reducing the overall pressure within the air. This is because the water molecules take up space in the air, leading to a decrease in the number of air molecules per unit volume.


How do the molecules of hot air differ from the molecules of cold air?

Hot air molecules have more kinetic energy and move faster than molecules in cold air. This results in hot air being less dense and having lower air pressure compared to cold air.


Air pressure becomes lowet as water molecules are addrd to the air because water molecules?

Air pressure becomes lower as water molecules are added to the air because water molecules have less weight.


Why compounds are molecules?

All compounds are made up of molecules. For example, salt, a compound, is composed of molecules (NaCl). By please do remember that molecules are not only limited to compounds. Meaning, there are also molecules that are not classified as compounds. The definition of a compound is a substance that is made up of two or more elements. A molecule is composed of two or more ATOMS connected by chemical forces. An example is oxygen air (O2). Oxygen air is a diatomic MOLECULE but it is NOT a COMPOUND.


Is air made of molecules?

Yes. Air is a mixture of many gas molecules.

when air is heated ,air pressure decreases because the molecules are


Does air molecules escape into space?

Air molecules do escape into space it depends on how heavy or hoe light they are. However, lighter molecules of air have greater velocities while heavy molecules of air has less velocities were gravity pulls the air downwards.
