What else can I help you with?
How do convection currents make a hot air balloon to rise?
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
Why does heating the air in hot air balloon make it rise?
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
Why is an hot air balloon called a hot air balloon?
A hot air balloon is called such because it is filled with hot air to make it rise. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to float upwards.
How does thermal expansion make a hot-air balloon rise?
It rises because when thermal engery is in the balloon it makes an expansion that makes the balloon fly
How do you make the air balloon rise higher?
By puting more hot air into it thus creating lift. hot air rises cold air lowers, so when the hot air is traped it has no were else to go but up so it brings the hot air balloon with it. And to decend a flap at the the top of the balloon opens by itsefl to let hot air out and to let you down.
Why does a balloon need hot air?
A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
What would heating the gas in an air balloon make the balloon rise?
Simple...hot air rises..
What chemicals from the periodic table make a hot air balloon rise?
There are many chemicals found in a hot air balloon to make it rise. The main elements/chemicals are Helium and Hydrogen.
Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?
He would heat it.
How does helium make a balloon rise when air doesn'?
Helium is lighter than air. So helium balloon rises in air.
Why would a hot air balloon pilot heat the air in the balloon to make it rise?
Heating the air in the balloon makes it less dense than the surrounding air, causing the balloon to become buoyant and rise. As the air inside the balloon cools, it becomes denser and the balloon descends. This process allows the pilot to control the altitude of the balloon.
Why can air balloon rise to the sky?
it can rise because of the helium and the gases help make it rise to the sky
How do convection currents make a hot air balloon to rise?
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
Why does heating the air in hot air balloon make it rise?
Hot air is lighter than cold air, so cold air sinks and hot air rises; that makes the hot air balloon rise (if the air around the hot air balloon is heated as well, it won't rise, or sink if in the air).
How do you make air lighter so that it will cause a balloon to rise?
To make air lighter, you can heat it up. Hot air is less dense than cold air, so it rises. When you heat the air inside a balloon, it becomes lighter than the surrounding air and causes the balloon to float upward.
What is the use of air in air balloon?
with out the hot air the balloon would not rise
Why is an hot air balloon called a hot air balloon?
A hot air balloon is called such because it is filled with hot air to make it rise. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to float upwards.
