Heating the air in a hot air balloon causes the balloons to rise is it a law or theory?

it is the law of gravity. Heating the air causes the molecules to speed up separate and the volume expands so the mass is less per sq inch and thus the pull of gravity from earth is diminished. The balloon rises to an area where the volume of surrounding gases is equal.

The following statement as a theory or a law heating the air in a hot air balloon cause the balloon to rise?
It is more like an observation or a hypothesis(depending on whether you have done the experiment or not).The law is the thermal expansion of gasses (Henry's Law).The theory is that a (lightweight) balloon filled with enough air that is hot enough will rise.
How much air fills a hot air balloon?
In theory, the larger the envelope on a hot air balloon (or the warmer the air inside compared to the ambient temperature outside), the more lifting force the balloon has. To answer your question, there is no single answer. Hot air balloons range in size from 70,000 cubic feet to over 200,000 cubic feet. (The "cubic feet" measurement refers to the volume of air inside the balloon envelope). Special shaped balloons can be enormous. The Energizer Bunny balloon is 15 feet taller than the Statue of Liberty. The ears alone are sixty feet...which is the height of an entire average-sized hot air balloon.
Why did the montgolfer brothers invent the hot air balloon?
Because their life ambition was to learn how to fly 'like birds' and the hot air balloon was their discovery. It was based on the theory that hot air rises. This is why hot air balloons are so big because just to lift a small amount of weight there has to be a lot of air.
Why is hydrogen no longer used in air balloons?
For small balloons like individuals often have for recreational use, hot air is much easier to control than either hydrogen or helium.For the occasional blimp, or long distance balloon trip, Helium, while somewhat heavier than Hydrogen, has proven to be far safer.The Hindenburg has proven the inherent dangers of using Hydrogen Gas in blimps. While, in theory, pure hydrogen is not explosive without the presence of oxygen, any rupture in the thin material separating hydrogen from the air atmosphere can prove to be deadly.
Is heating the air in a hot-air balloon cause the to rise a theory or a law?
The law is called Law of Buoyancy, matter with less density tries to raise above the matter with high density. When air is heated, the volume increases and density decreases. Since the air around the ballon is at a lower temperature and the density is higher, the air in the baloon tries to move up thus lifting the baloon.
Can a bunch of balloons hold up an elephant?
In theory, yes. Especially if they're of the hot air balloon variety and there are enough of them.

Will a balloon deflate faster in warm or cold temperatures?
A helium balloon of the same material will deflate faster. Helium molecules are smaller than those in regular air, so they'll seep through tiny holes and imperfections in the skin of the balloon faster. When using the standard PIN analysis - both helium and common air balloons were found to deflate at the same rate. To the naked eye, both balloons stuck with a pin deflated with a pop. However, if the balloons are left intact, the helium balloon will deflate faster. This is because the helium molecules are small enough to pass through the rubber balloon, and they gradually leak out.

What is difference between modern and old hot air balloons?
at the very start, the first balloonists burnt materials onboard the balloon to generate heat to propel the envelope into the air. Theory then became obsolete as gas and helium designs were introduced as it was considered safer and more reliable than flying with an open flame.
Who rejected vital force theory?
Friedrick Wohler rejected this theory in 1828 by heating ammonium cyanate in laboratory.
Helium balloons vs carbon dioxide?
Helium balloons deflate faster because the molecules are smaller and can seep through the smallest of holes. ... Except that this isn't what happens. Try inflating some latex balloons with CO2 (use a chemical reaction with baking soda to generate it) and compare them to helium balloons. It's amazing to see how quickly the CO2 balloons shrivel up. Note: balloons made of mylar or other materials might behave more in line with theory, but CO2 escapes from latex balloons quickly.
