What else can I help you with?
Why did the inflated balloon move when the air inside it escapes?
When the air inside the balloon escapes, it creates a difference in air pressure between the inside and outside of the balloon. This pressure difference causes the balloon to move in the direction of lower pressure, which is typically outwards.
What is the difference between a water balloon and a normal balloon?
A water balloon is filled with water, and other balloons are filled with air or helium.
What is the difference between a hot air balloon and an airplane?
One difference is that a hot-air balloon is uncontrollable and can't be maneuvered in different directions while a plane can move in various directions.
Is there a difference between water pressure and air pressure when it comes to popping a balloon?
No.
What friction aids a hot air balloon?
Friction between the hot air inside the balloon and the balloon envelope helps to create lift by making the balloon envelope less dense than the surrounding air. This difference in density causes the balloon to rise.
Does blowing air in a balloon involves a push?
Yes, blowing air into a balloon creates a pressure difference between the inside and outside of the balloon, causing the balloon to expand. This expansion is a result of the air molecules inside the balloon being pushed outward by the force of the air being blown in.
WHAT ARE THE TWO FORCES ACTING ON THE hot AIR BALLOON?
The two main forces acting on a hot air balloon are buoyant force, which lifts the balloon due to the density difference between the hot air inside the balloon and the cooler air outside, and gravity, which acts to pull the balloon downward.
Will a difference in air temperature affect the size of a balloon?
Yes, a difference in air temperature can affect the size of a balloon. When air temperature increases, the air inside the balloon expands, causing the balloon to inflate. Conversely, when air temperature decreases, the air inside the balloon contracts, causing the balloon to deflate.
Is the pressure difference between the top of the balloon responsible for giving the hot air balloon a lift?
Yes, the pressure difference between the inside and outside of the balloon causes it to rise. As the air inside the balloon is heated, it becomes less dense than the surrounding air, creating lift due to the pressure difference.
How does a hot air balloon float with people in it?
Just the density difference between the balloon and surrounding atmosphere is so great that the balloon is able to lift itself and people.
What is the energy transformation of a hot ballom?
A hot air balloon transforms thermal energy (from the heat source used to inflate the balloon) into kinetic energy as it moves through the air. The balloon rises due to the difference in temperature between the air inside the balloon and the surrounding cooler air, which creates buoyancy.
What is the difference in the height of the balloon after ten minutes and the height of the balloon after sixty minutes?
There is no difference at all if the balloon is not inflated or inflated with air.
