How the hot air balloon can rise up into the air even through it doesm't have a motor?
A rubber ball rises up in the water because it is full of a substance (rubber) that is lighter than the same volume of water. A hot air balloon rises up into the cool air because it is full of a substance (hot air) that is lighter than the same volume of cool air. The hot air balloon floats in cool air, just like the rubber ball floats in water.
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 causes hot air balloons to fly?
Usually only balloons that are filled with helium will float. Helium is a gas that is lighter than air, so causes the balloon to fly. Note that if you blow a balloon yourself, it will just float to the ground. There are also hot air balloons in which the air is heated by an on board heater. Hot air, being lighter than cold air, rises and lifts the balloon. When the air cools, unless it is reheated, the balloon descends.
Why does a hot air balloon rise when it is heated?
Hot air has less density than air at ambient temperature. And just like with water, something that is lighter than the media that surrounds it will try to float to the top.
What force keeps a hot air balloon up in the air?
It is because hot air is lighter than cool air. Because it has less mass per volume unit, the hot air needs to be propelled upwards into the fabric using the burner. To lift 1000 pounds of weight, you'll need about 65000 cubic feet of heated air. They simply float with the wind and are not directed, until the pilot lands the balloon.
Why does it have to be hot air and not cold inside the envelope of a hot air balloon?
hot air rises; it is lighter than cool air It does not have to be Hot Air inside the balloon, unless you want that Balloon to rise up.Hot Air is less dense than Cold Air and hence the former is lighter.
Why warm air rises and cool air sinks.?
hot air is lighter than cold air so, it gose up

Why was the airplane harder to invent than the hot air balloon?
The balloon is lighter than air.
Why is the air temperature near the ceiling of a room tends to be warmer than near th floor?
The hot air is lighter than the cool air so it floats to the ceiling.:)
What are some lighter than air aircrafts?
blimp or hot air balloons are lighter than air crafts
When balloons are filled with this they are lighter than air.?
Hot air, hydrogen or helium are lighter than cold air.
When balloons are filled with this they are lighter than air?
Hot air, hydrogen or helium are lighter than cold air.
Is a hot air balloon lighter or heaver then air?
The actual balloon isn't lighter than air, the only reason hot air balloons rise is because they are filled with hot air, which is lighter and less dense than cold air, causing it to rise. :)
Is warm air dense?
No, warm air is lighter than cold air because hot air rises and cold air stays in the same place.
What is in a hot air balloon to make it fly?
Hot air! Hot air is lighter than cold air.
Is hot air liter or heavier than cold air?
Hot air rises, so is lighter than cold air.
