Rockets need to carry their own supply of oxygen because they travel through the vacuum of space where there is no atmosphere to provide oxygen for combustion. By carrying their own oxidizer, such as liquid oxygen, rockets can generate the thrust needed to propel themselves forward.

How does perfluorooctyl bromide supply oxygen to tissues?
Perfluorooctyl bromide (PFOB) is a synthetic oxygen carrier that dissolves a large amount of oxygen which can be released to tissues in need. When PFOB is administered intravenously, it can carry oxygen in the bloodstream, allowing tissues to extract the oxygen they need for metabolism.
How does oxygen affect how long a candle burns for?
Oxygen is necessary for combustion to take place. When a candle burns, it reacts with oxygen in the air to produce a flame. Increasing the oxygen supply will result in a hotter and more efficient burn, causing the candle to burn more quickly. Conversely, reducing the oxygen supply will cause the flame to burn more slowly or even extinguish.
Do the lungs bring oxygen into blood?
Yes, the lungs take in oxygen from the air we breathe and transfer it into the bloodstream through tiny blood vessels called capillaries. Oxygen-rich blood is then carried to the rest of the body to supply cells with the oxygen they need for energy production.
Does conifers give off oxygen?
No!
Is hydrogen peroxide used as rocket fuel?
In outer space there's no oxygen, so no combustion can take place unless you bring along your own. Hydrogen peroxide is a convenient way to do that: it's a strong oxidizing agent and it's considerably more dense than oxygen gas. You could liquify oxygen to make it more dense, of course, but then you need either stronger, thicker walls to withstand the pressure in the tank or heavy refrigeration equipment, both of which increase the weight of the rocket. Hydrogen peroxide doesn't need to be compressed or refrigerated, since it's already liquid.
Why do space rockets have to carry a supply of oxygen?
In space there is no oxygen. Space is a vacuum. All things like a rocket going to space, require a fuel to burn, oxygen and a heater. Since there is no oxygen is space they need to provide it for them. Meaning the reaction can take place correctly.
Why do rockets engines in space have to carry their own oxygen?
Fire needs oxygen in order to burn, and there is no oxygen in space, so rockets must take oxygen with them.
What gases do rockets use when they take off?
they are hydrogen, nitrogen and oxygen
Trees need some oxygen to grow. Do they take in some through the air or do they take it in through the soil via water?
The leaves supply almost all of the oxygen, so through the air.
Where do fireworks and space rockets get their oxygen from?
They take it with them in some form or another. Fireworks use oxidizing salts such as various nitrates and chlorates. Solid fuel rockets generally use ammonium perchlorate as an oxidizer while liquid fuel rockets carry liquid oxygen.
How does aquatic life take its oxygen supply?
It takes in water (which has oxygen in it) through the gills, takes out the oxygen, and then uses it.
Does trachea take in oxygen?
Neither trachea nor bronchial tree take in any oxygen from the air. It gets oxygen via blood supply.
Do oysters need oxygen to breathe?
fishes take in water and remove oxygen from it.....thats how they breathe....
Why will a rocket work in space where there is not enough air for other vehicles to operate?
Vehicles such as airplanes and cars rely on oxygen from the air to burn their fuel. Rockets take the oxygen with them.
Why do astronauts take oxygen with them into space?
Liquid oxygen and liquid nitrogen are carried on board in two systems of pressurized tanks. The cabin pressurization system combines the gases in the correct mixture at normal atmospheric pressure. While in orbit, only one oxygen system and one nitrogen system are used to pressurize the orbiter. During launch and landing, both systems of each gas are used. For more info about the space shuttle, see the Related Link below.
Why do astronautts on the moon kneed to take oxygen with them?
Astronauts on the moon need to bring their own oxygen supply because there is no breathable atmosphere on the moon. Without a source of oxygen, they won't be able to breathe and survive on the lunar surface.
How do rockets off?
rockets take off when gases are shot out of the opposite direction with great force. The gases are conctrated by being forced through a small nozzle Liquid hydrogen and liquid oxygen is the fuel.
