What is the use of oxygen in the rockets?
It is used as oxidant in the rockets.
How can you use a balloon with a negative charge to find out whether the charge on another balloon is positive or negative?
You can tell if the negative balloon attracts or repels the other balloon. If it attracts the balloon then it is a positive balloon. If it repels the balloon then it is a negative balloon.
How does temperature affect the size of a balloon?
When the temperature is colder the particles in the balloon travel slower, making the balloon not able to increase in size it decreases.When the temperature is hot it allows the balloon to expand because the particles in the balloon are moving rapidly. in conclusion the the cold makes the balloon decrease in size and the heat allows it to expand.
Is a helium balloon a solid?
A helium "balloon" is composed of two parts: the SOLID rubber balloon skin, and the GASeous helium. So the balloon part itself is a solid.
Which gas is pumped into a balloon?
Helium gas is pumped into a balloon.
Can you fly to the moon with a balloon. Or a plane?
I doubt it. In order for a balloon to work you have to have atmosphere. Once you leave the atmosphere of the earth, you can drift in any direction. The space craft that we use has thrusters and rockets that will steer you in the direction you want to go. Balloons are at the mercy of the wind.
Why do rockets take off?
Rockets take off to carry things (called payloads) into space. Do you mean 'how' do rockets take off, or how do rockets work?
What are balloon rockets made out of?
1 balloon (round ones will work, but the longer "airship" balloons work best)1 long piece of kite string (about 10-15 feet long)1 plastic strawtapeTie one end of the string to a chair, door knob, or other support.Put the other end of the string through the straw.Pull the string tight and tie it to another support in the room.Blow up the balloon (but don't tie it.) Pinch the end of the balloon and tape the balloon to the straw as shown above. You're ready for launch.Let go and watch the rocket fly!.So how does it work? It's all about the air...and thrust. As the air rushes out of the balloon, it creates a forward motion called THRUST. Thrust is a pushing force created by energy. In the balloon experiment, our thrust comes from the energy of the balloon forcing the air out. Different sizes and shapes of balloon will create more or less thrust. In a real rocket, thrust is created by the force of burning rocket fuel as it blasts from the rockets engine - as the engines blast down, the rocket goes up!
What causes rocket propulsion?
For every action, there is an equal but opposite reaction. It you blow up a balloon and don't tie the end, the air inside the balloon is pushing against all of the balloon equally. When the untied end is released, air pushing out the back causes an equal affect of pushing on the front and the balloon moves forward. Rockets work in the same manner. Instead of air, they use combustible fuel for their force.
Will rockets work in space?
Yes. The space shuttle uses rockets in space to manuever.
What are some animals that fly?
birds
Do rockets work better in space or in air?
Rockets generally work better in the space as compared on air. This is because there is no air resistance on the space.
Do model rockets and real rockets work the same?
Yes, both work by action/reaction. Model rockets are just much smaller, thus have much less fuel, so can't go near as high or as far.
What law is the reason rockets work?
Galileo's law
Can you give me info on lemon juice rockets?
it does not work
How do you land a hotair balloon?
Well All hot air balloons have a variable release valve in the top of the balloon which the pilot can use to control the altitude of the balloon..This valve when opened to a certain point allows hot air to slowly escape from the top of the balloon and the balloon will slowly decend,the exchange is controlled so the balloon maintains its size...by use of the release valve and the burners the pilot can control the rate of decent to a nice soft landing....The release valve is also used to quickly deflate the ballon once it has landed...
What happens when the amount of force in a balloon changes?
As in balloon-powered rockets, a reduction in energy within the balloon can be accompanied by force exerted to move the balloon, or another object. The energy stored in a balloon is in the form of higher pressure stretching it out. If the balloon has an opening, the air will be forced out until the balloon regains its unstretched shape. At that point, air inside the balloon is at the same pressure as the air outside the balloon. Other containers can also store air at a pressure higher than the outside air. This can also provide force when the stored energy is released.
