What else can I help you with?
How will the air at the top of a mountain be different from the air at the base?
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.
What does the burner do to the density of the air in a hot air balloon?
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.
Most of the air you breathe in goes back into the atmosphere when you exhale?
When you breathe in, you take in oxygen and when you breathe out, you release carbon dioxide. Most of the air you breathe out is composed of nitrogen and oxygen with a slightly higher concentration of carbon dioxide than in the atmosphere. The oxygen you inhale is used by your cells for energy production, while the carbon dioxide is a waste product that is released back into the air.
Does the space station have to fill up with air or oxygen?
It is filled with air, as prolonged exposure to pure oxygen is harmful to humans.
Why do you exhale more water vapor than you inhale?
When you exhale, you release moisture from your lungs into the air as water vapor, which is why the exhaled air contains more water vapor than the inhaled air. This moisture comes from the air you breathe in, as your body extracts oxygen and releases carbon dioxide and water vapor during the process of respiration.
Does inhale air has more oxygen or exhaled air?
Inhaled air has more oxygen compared to exhaled air. When we inhale, we take in fresh oxygen from the environment to use for cellular respiration. As we exhale, we release carbon dioxide and the remaining oxygen that was not used by the body.
What element does iron react with in damp air?
Iron reacts with oxygen in air to for rust.
Does a nail rust faster when the air is damp or dry?
A nail will rust faster in damp air because moisture accelerates the corrosion process by providing the water and oxygen needed for rusting to occur. Dry air slows down the rusting process by limiting the availability of water and oxygen.
Why is air in the desert rich in oxygen when there are no plants?
The oxygen content of air in deserts is not necessarily higher than in other regions. However, deserts can experience high temperatures and low humidity, which can make it feel like the air is richer in oxygen when, in fact, it is the dryness and heat that are creating this sensation.
Why do lungs work more efficiently than gills in extracting oxygen from air?
Lungs work more efficiently than gills in extracting oxygen from air because they have a larger surface area for gas exchange and a more complex structure that allows for a more efficient transfer of oxygen into the bloodstream. Additionally, the respiratory system in mammals is more adapted to extracting oxygen from the air, which is a richer source of oxygen compared to water.
What is heavier damp air or dry air?
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.
Why is it different when the composition of the air as it enters the lung compaerd to when it leaves the lung?
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.
Why does the mass of iron go up when left in damp air for a few days?
The mass of iron can increase when left in damp air for a few days due to the formation of rust (iron oxide) on its surface. Rust is a combination of iron, oxygen, and water, which adds to the overall mass of the iron object.
Does cold air contain more oxygen than warm air?
Yes, cold air typically contains more oxygen than warm air. This is because cold air is denser and can hold more molecules, including oxygen.
Why is the oxygen in the air higher than the carbon dioxide in the air?
no
What is damp stale air?
A noun for damp, stale air is must or mustiness; the adjectives are musty or dank.
What is blackdamp?
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.
