What determines if gases or vapors are lighter or heavier than air?
The molecular weight of the gas or vapor plays a key role in determining whether it is lighter or heavier than air. Gases or vapors with lower molecular weights are typically lighter than air and will rise, while those with higher molecular weights are heavier and tend to sink. Temperature and pressure can also impact the behavior of gases and vapors relative to air.
What is the volume of gases that are made up of moelcules in 100cm3 of air?
The volume of gases in 100 cm3 of air depends on the composition of the air. Typically, air is approximately 78% nitrogen, 21% oxygen, and 1% other gases. Each gas will occupy a volume proportional to its mole fraction. Given the molecular weights of nitrogen (28 g/mol) and oxygen (32 g/mol), you can calculate the volumes using the ideal gas law.
You can separate air into two different substances by density what is air?
Air is a mixture of gases, primarily composed of nitrogen (about 78%), oxygen (about 21%), and trace amounts of other gases like argon, carbon dioxide, and water vapor. Its components can be separated by density differences, as various gases have different molecular weights. For example, gases like carbon dioxide are denser than nitrogen and oxygen, allowing for potential separation. However, in practice, air is usually treated as a homogeneous mixture rather than separated into its individual components.
Why do noble gases in balloon float in air?
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
Air is primarily composed of nitrogen and oxygen gases which state of these gases can conduct electricity?
These gases are not conductive.

True or false Gases with high molecular weights diffuse more slowly than gases with lower molecular weights?
True. Gases with high molecular weights have slower diffusion rates compared to gases with lower molecular weights due to their larger mass and lower average speed of the molecules.

How does Argon displace oxygen- and moisture-containing air?
Argon is denser than air, so when it is introduced into a space, it sinks and pushes the oxygen- and moisture-containing air upwards and out. This displacement process occurs because of the differences in molecular weights of the gases.

What gases pollute air?
What gases cause air pollution
If the gases weren't in the air would we die?
Yes. The gases ARE the air.
Why do noble gases in balloon float in air?
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
Why are thedifferent gases in air important to life on earth?
Without different gases there will be no air, if there is air, how can oxygen travel?
What is a word for water or air dirty with gases or chemicals?
Water or air dirty with gases or chemicals is polluted water or air.
Is there something that is magnetic on air?
Gases, and so air which is a mixture of gases (at normal temperature and pressure) are not magnetic.
What layer of the atmosphere has layered gases and thin air?
The atmosphere has layered gases. It also has thin air.
