What makes the hot air balloon go up and down?
A hot air balloon goes up when the air inside the balloon is heated, causing it to become less dense than the surrounding air. This creates lift. To descend, the air inside the balloon is allowed to cool, increasing its density, which causes the balloon to lower.
Why do we need hot air balloons?
It needs hot air because hot air goes up and cold air goes down. Hot air makes it go up.
What powers hot air balloon?
Hot air balloons are powered by the flame from a propane burner that heats up the air inside the balloon, which lowers the density of the air inside by heating it up and accellerating the particles. Lower density (hot) air will rise above air with higher density (the air outside) which is why they have a height limit, as the average density of air goes down the higher you go.
How do you control a hot air balloon?
With great difficulty. Up and down are fairly controllable, because you can heat the air more to go up, or let some of it out to go down. Lateral steering, however, is impossible. One has to go gradually upwards and hope to find a layer of air which is moving in the right direction.
Why does a hot air balloon only go up when it is hot air?
Hot air is less dense then the surrounding air, meaning it's lighter then regular air, allowing it to naturally lift. If something catches that lifting air, and the air is so light that it can lift the required weight up, then it will lift. That's why a hot air balloon requires hot air to lift.
How does a hot air balloon go up and down?
Heat rises of it makes the ballon rises
What makes the hot air balloon go up and down?

Does hot air go up or down in relation to its surrounding environment?
Hot air rises in relation to its surrounding environment. This is because hot air is less dense than cold air, causing it to be buoyant and move upwards.
Will cool air goes up?
hot air goes up, cold air goes down.
Why do we need hot air balloons?
It needs hot air because hot air goes up and cold air goes down. Hot air makes it go up.
Why flames of a fire rise even though gravity pull thing downwards?
Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.Gravity pulls denser air down, this pushes the lighter hot air, from the fire, up.
Why are acs placed at a height?
during the the process of convection the hot air is lighter so the hot air rises up and the cold air is heavier so air conditioners cool down that hot air which has rose up
Why does hot air balloons go up?
1000feet

When you smok dose the smok go up or down?
"Smoke", strictly speaking, consists of particles of ash carried on the hot air from burning. Since hot air is less dense than cold air, it rises as it is displaced by the heavier cold air.
How do you control a hot air balloon?

What it is called when hot air goes and cold air goes down?
This process is called convection. Hot air rises because it is less dense than cold air, creating a cycle where hot air goes up and cold air goes down, creating air currents.
