Which force allows hot air balloons to fly?
Hot air balloons fly due to the principle of buoyancy. As the air inside the balloon heats up, it becomes less dense than the surrounding cooler air. This difference in density creates a lifting force that allows the balloon to float in the air.
Can a deflated balloon be blown up again?
Yes, a deflated balloon can be blown up again by adding air or helium to it using a pump or by blowing into it with your mouth. The balloon will expand and return to its original shape and size when inflated.
How does convection explain the ability to fly hot air balloons?
Convection explains the ability to fly hot air balloons because hot air rises due to its lower density compared to cooler air. As the air inside the balloon heats up, it becomes less dense and creates buoyancy, lifting the balloon. This convection process allows the balloon to float in the cooler air above.
What do you blow up a balloon to make it fly?
Helium gas is typically used to fill balloons to make them float or fly. Helium is lighter than air, so it causes the balloon to rise due to the difference in density between the helium gas inside the balloon and the surrounding air.
Can balloons pick up sand?
No, balloons cannot pick up sand because their buoyancy is not strong enough to lift particles as heavy as sand. Balloons are typically filled with helium or hot air, which is not capable of lifting denser materials like sand.
What can you do with balloons?
you can play with them and blow them up and fill them with water and lots of balloons can make you fly
Which is stronger A blown up balloon or a balloon waiting to be blown up?
I'm not very sure but I think thatthe balloon waiting to be blown up would be stronger, because inflated balloons can often pop easily.
The are 486 balloons that need to be blown up if there are 18 volunteers how many balloons would each volunteer need to blow up?
486/18 = 27 ballons each
Does stater bros sell blown up latex balloons?
Yes, Stater Bros typically sells blown-up latex balloons, particularly for celebrations and special occasions. They often have a selection of party supplies, including balloons in various colors and designs. It's best to check with your local Stater Bros for availability, as stock may vary by location.
Where do balloons go when they fly away?
Balloons that fly away typically end up in the atmosphere where they can eventually deflate and fall back to Earth. This can have harmful effects on wildlife and the environment as the deflated balloons often end up as litter. It is important to properly dispose of balloons to prevent this from happening.
How fast can pathogen carrying droplets fly out of your mouth when you sneeze?
The droplets can fly out of your mouth at up to 100 mph.
How did jaws die in jaws?
blown up by the shooting of a propane tank in his mouth
There are 486 balloons that need to be blown up for the spring dance at school If there are 18 volunteers how many balloons would each volunteer need to blow up?
easy, divide 486 by 18, i could do that without a calculator if i could be bothered, but by using a calculator, it is 27 balloons each.
How long will balloons float filled with exhaled air?
When a balloon is blown up by mouth, it will not float, but fall to the ground. This is because the air inside is the same density as the air outside. For a balloon to float up into the air, it must be inflated with a gas that is lighter than air - such as helium.
How do you change the color of your balloons in Mario Kart ds?
First make sure you have no more then 2 balloons blown up, then find a mushroom boost, and when you see another player coming towards you use the boost and smash into them, and you will steal one of their balloons!
Where do hot air balloon fly form?
Hot air balloons can pick up and fly from just about anywhere. As long as the surface is flat a hot air balloon can fly from it.
Why do balloons fly with helium and not with normal human oxygen?
because helium is lighter than air,therefore, when letting go of the balloon it will fly up
