How do astronauts get oxygen into space?
They carry it with them on board.
Why do you never see the faces of the astronauts?
Astronauts in spacesuits wear helmets with opaque visors, which protect them from the harsh conditions of space. The visors also help regulate temperature and provide oxygen. Additionally, the visors shield their eyes from glare and harmful radiation.
How would you save extra oxygen and air that would continuously provide fresh air?
To save extra oxygen and continuously provide fresh air, one could implement a combination of indoor plants and efficient ventilation systems. Certain plants, like snake plants and peace lilies, naturally produce oxygen and improve air quality through photosynthesis. Additionally, employing a heat recovery ventilation system can help maintain fresh air circulation while minimizing energy loss, ensuring a consistent supply of oxygen-rich air. Regularly monitoring air quality and adjusting plant selections can further enhance the effectiveness of this approach.
What is a continuously burning fire?
A continuously burning fire is a fire that has a fuel source that allows it to keep burning without extinguishing. This can be achieved through a consistent supply of oxygen and fuel to the fire. Maintaining a continuously burning fire requires careful management and monitoring to prevent it from spreading uncontrollably.
What makes the concentration of oxygen low in the alveolus?
The concentration of oxygen in the alveolus is low because it is continuously being taken up by the blood in the pulmonary capillaries for oxygenation. As a result, the oxygen level in the alveolus decreases, creating a concentration gradient that promotes the diffusion of oxygen into the bloodstream.
Why do you need spacesuit and oxygen tank?
Spacesuits and oxygen tanks are needed in space because there is no atmosphere to provide oxygen for astronauts to breathe. Spacesuits also protect astronauts from extreme temperatures, radiation, and micrometeoroids. Without these, astronauts would not be able to survive in the harsh conditions of space.
What two gasses are used in spacecraft to provide breathing air for astronauts?
oxygen and nitrogen
How do astronauts survive without oxygen?
Astronauts cannot survive without oxygen; they rely on life support systems in their spacecraft or space suits to provide a continuous supply of breathable air. These systems use tanks of compressed oxygen and can also recycle carbon dioxide exhaled by astronauts. In emergencies, astronauts can use backup oxygen supplies to ensure they have enough air to breathe. Without these systems, they would quickly suffocate in the vacuum of space.
What happen the astronauts without oxygen?
Without oxygen, astronauts would not be able to breathe and would suffer from hypoxia, which can lead to unconsciousness and eventually death. The lack of oxygen in space can also cause damage to the brain and other vital organs. Special equipment, like space suits and spacecraft, are designed to provide astronauts with a controlled environment that includes a supply of oxygen to prevent these issues.
Do I need oxygen to survive in space?
Yes, you need oxygen to survive in space because there is no breathable air in space. Astronauts rely on spacesuits or spacecraft with life support systems to provide them with oxygen to breathe.
How do astronauts breathe?
Astronauts breathe using the life support systems on their spacecraft or spacesuits. These systems provide a controlled supply of oxygen for them to breathe while in space. Inside the spacecraft, the air is managed to ensure astronauts have a safe and breathable atmosphere.
Why are space suits required for space walks?
To provide a pressurized environment and oxygen to keep the astronauts alive, as well as regulating temperature.
Why do spacecraft need internal oxygen supply?
Spacecraft need an internal oxygen supply to provide a breathable atmosphere for astronauts during space travel. Since there is no oxygen in space, spacecraft must carry their own supply to support human life. This ensures that astronauts have the necessary oxygen to breathe and carry out their activities while in space.
Why do astronauts wear a hat?
Astronauts wear helmets or space suits, not hats, to provide protection in space from extreme temperatures, micrometeoroids, and radiation. The helmet also ensures they have a stable supply of oxygen and communication.
How will astronauts get oxygen out of space?
They need to take it with them. There is no oxygen in space
How would you breathe inside and outside of the space or in the spacecraft?
Inside the spacecraft, astronauts breathe normally as the spacecraft is equipped with systems that provide oxygen. In space, outside of the spacecraft's protective environment, astronauts rely on their spacesuits, which have life support systems that provide oxygen for breathing. Additionally, they can also re-enter the spacecraft if needed to breathe safely.
How do astronauts get oxygen in space?
Astronauts bring tanks of oxygen with them when they go into space. The space suits they use to make space walks also have small oxygen tanks on them.
