What causes hot air balloons to fly?
Hot air balloons fly because of the principle of buoyancy. The balloon is filled with hot air, which is lighter than the surrounding cooler air. This temperature difference creates lift, causing the balloon to rise. By controlling the temperature of the air inside the balloon, the pilot can control the altitude.
Is it easier to fly a plane in the cold or in the hot?
Flying in colder temperatures generally creates better flying conditions as cold air is denser, providing more lift and engine performance. In contrast, hot temperatures can reduce engine performance and lift, making it more challenging to fly, especially during takeoff and landing. Pilots often prefer flying in colder conditions for better aircraft performance.
Could a fly 'fly' in a vacuum?
No, a fly would not be able to fly in a vacuum because it relies on air resistance and pressure to generate lift and maneuver in the air. In a vacuum, there would be no air molecules for the fly to interact with, so it would not be able to fly.
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.
What do these 3 words have in common weight fly and sand?
The words weight, fly and sand have "fly" in common, because together they can form other words. Their direct relationship is: fly, fly weight, and sand fly.
Does heated air produce pressure?
Yes! The heated air molecules always wants to fly upwards because of being lite. We can take the example of a ballon filled with air. When ballon is heated the pressure increases and ballon brusts. This proves that hot air exerts pressure.
How are balloons and airplanes alike?
They both fly. The only difference is that a ballon has helium to make it fly but air planes use gas to make it fly.
Is the hot air balloon still used?
Yes, they are. Many people fly them for a business or hobby. The first air type spy mission was with a hot air ballon in the civil war.
How hot air baloons are able to float?
hot air baloons are able to fly because the hot air that is released in to the ballon wants to get out so there for it keeps pushing and that is how a hot air balloon floats
How can you kill nats in your home your self?
What you have to do is... *Kill all of the eggs, just wash them away or spray them with bleach * Then your have to keep the air on, make your house really cold... (they wont fly around in the cold, they will simply die) After that you should be okay.
Do planes fly easier in cold or warm air?
Planes fly better in warm weather because if it is cold then fog builds up and they want be able to see also the wind will be pushing them back so its better to fly in warm air.
Why traces of smokes when aircraft fly in high altitude?
That is condensation from hot engines in cold air.
When your ears pop is there a tiny bit of air that comes out?
yes but is really so small of air that when you put baby powder on your ear it wont fly off
Do baseballs fly farther when cold as opposed to hot?
i don't know if the temperature of the baseball itself affects it's flight time, but i have noticed that balls do fly futher when the -air- is hot, as opposed to cold
Why wont your air hogs havoc razor helicopter fly?
The helicopter might not fly because the battery is dead and needs to be charged or because you have the remote and helicopter on different frequencies.
How come hot air balloons fly better in cold weather?
because the air inside the balloon has to be warmer than the air outside the balloon in order to fly higher, so if the air is warm it takes longer to fly higher so if you stop flying higher eventually the air will escape from the balloon making you sink which for obvius reasons is bad.
How cold does it when your in a jet in the air?
The outside air temperature at 39,000 feet (a common altitude for jet airliners to fly) is about 45 degrees below zero.
