hot air is richer in oxygen than damp air because when you sex a girl it is hot
The air at the top of the mountain is less dense, meaning there are less particles of oxygen in a certain are than on the ground. It is harder to breathe because the air is so thin, there is not enough oxygen to breathe normally until you get used to it.
The intense heat of the burner alters the atomic nucleus of the oxygen atom into a synthetic helium atom causing the balloon to rise. The helium atom is less dense than the original oxygen atom.
It is filled with air, as prolonged exposure to pure oxygen is harmful to humans.
air (oxygen) does not exist in space. that's why astronauts have suits with oxygen tanks.
No, because people can only breathe with Earth air (which mainly consists of Nitrogen and Oxygen), and moon atmosphere has no Nitrogen or Oxygen.
Inhaled air is richer in oxygen than exhaled air.
Iron reacts with oxygen in air to for rust.
it rusts faster when it is damp cause the moisture of the damp and oxygen when they meet they create rust
Iron rusts because it reacts with oxygen. The oxygen in water reacts with iron quicker than oxygen in air, and the air outside is often damp, and there is the rain as well.
It forms rust by binding with oxygen. The added weight is the oxygen.
The air that enters the lungs is richer in oxygen when it enters the lungs. when it leaves it has more carbon dioxide and less oxygen as the lungs expel carbon dioxde and some unused oxygen.
Dry air is "heavier" than moist air, that is, it is denser. The water molecules in humid air do not fit in between "air" molecules (diatomic nitrogen and oxygen in a 79:21 ratio), they replace them, as per Avogardo's number of molecules in a mole of a gas. One molecule of diatomic nitrogen has a mass of 32 AMU and of diatomic oxygen, 28 AMU. A water molecule only has a mass of 16 AMU. Don't believe it? Think about it: a high pressure system is dry air and is higher pressure because it is a sinking air mass. It sinks because it is heavier.
Blackdamp is another term for choke damp - an asphyxiant found in enclosed places such as mines and sewers after oxygen has been removed from the air.
A noun for damp, stale air is must or mustiness; the adjectives are musty or dank.
no
For a fish, it is better. Since I don't have gills, I consider oxygen in air better.
Stythe gas is an asphyxiant that reduces the available oxygen content of air to where animals or humans can not survive in it. It is also called Black damp.
