What kind of heat transfer causes a hot air balloon to rise?
Convection.
Why does heat rise and how does cold drop?
Cold air is compact air Hot air is less dense than cold air Ergo, hot air rises ; cold air sinks
What physical properties allow hot air balloons to fly?
Heat, the heat from the flames below the balloon cause the balloon to rise.
How does particle theory explain the formation works in a hot air balloon?
A gas burner is used in the hot air balloon to heat air. When heat is applied, particles tend to expand. Due to this the air surrounding the balloon is cooler than the air inside it, making it to rise.
What is the difference between a helium balloon and a hot air balloon?
A helium balloon does not need energy to rise in the air. A hot air balloon needs fuel to rise in air. That is it needs heat energy to rise in air.i love Pizza squares i hope they put helium in then one dayHelium relies on the fact that helium is lighter than air. Hot air balloons rely on the fact that hot air has less volume than cold air and is lighter than the air around it. hot air balloons use hot air to cause the balloon to lift as helium balloons use a special gas to cause lift
What property causes a hot air balloon to rise?
heat
Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?
He would heat it.
What heat sources make things rise?
Fire makes things rise as it is a very strong source of heat. So does hot air. Fire causes hot air and because hot air is lighter than cold air, it rises. Is that good? (my first answer X3)
Does the sun heat air and hot air rise?
Yes on both counts. But hot air balloons need considerably more help - they use propane burners to heat the air inside the balloon.
Why does air rise at the equator?
because the equator is hot and heat rises the air gets hotter and rises
What kind of heat transfer causes a hot air balloon to rise?
Convection.
What causes hot air to rise?
Hot air is lighter than cold air, so it rises up. Ex. A hot air balloon rises up because we heat the air and it goes up.
Why does heat rise and how does cold drop?
Cold air is compact air Hot air is less dense than cold air Ergo, hot air rises ; cold air sinks
What physical properties allow hot air balloons to fly?
Heat, the heat from the flames below the balloon cause the balloon to rise.
Why does a hot air balloon rise in cold air?
The fire raises it not the heat of the temperature in the air that day. The wouldn't put a hot air balloon up when it was freezing cold or heaps windy.
How does heat make a hot air balloon go up?
Hot air rises. By heating the cool air in the balloon using a propane heater, heats the air and makes the balloon rise
How does a hot air balloon stays in the air?
A hot air balloon can stay in the air because the hot air is less dense than cool air. The hot air that is blown into the balloon causes it to rise and a burner is used to heat the air inside of the balloon to keep it floating.
