By radiating energy, the heat excites air molecules to expand, within the confined space of the balloon's lower density and over all mass, causing the whole thing including the container to float.
Hot air is lighter (less dense) than cool air, so it rises.
Because the cool air is denser it occupies less volume. The cooler, denser air will slide down beneath the warm air mass, thus providing lift to the balloon.
If you heat a gas such as air, it will expand - more volume for the same mass. This means it will be less dense - less kilograms per cubic meter for example. Being less dense than the surrounding air, it will tend to float - but of course, the upwards force must be enough to compensate the balloon's weight.
Because hot air rises. Period. Nothing fancy. The air in the balloon would be hotter than the air around it, so it will rise.
Hot air is less dense than colder air, therefore the hot air balloon will float on the cooler air surrounding it.
What else can I help you with?
How is the average density of a heluim balloon be changed to make it rise float at a constant level and sink?
you would have to deacrease the density. By doing so, you can float. I don't know bout constant level, but because the air in the balloon is more dense than outside air, the balloon will sink in air. p.s. i know you s.j.v students are probably reading this :)
What gas can make a balloon float Is it hydrogen or Nitrogen or Argon or Chlorine?
Hydrogen can make a balloon float. Nitrogen, argon, and chlorine will not. However, hydrogen is combustible and in a balloon that cam near an ignition source, could produce a fire or explosion. The preferred gas for balloons, if cost is not an issue, is helium, which does not burn and is still very light.
How can you tell if a chemical reaction has taken place when a hot air balloon flies?
When a hot air balloon flies, the chemical reaction that occurs is the heating of the air inside the balloon, causing it to expand and become less dense than the surrounding air. This creates lift, allowing the balloon to rise. You can confirm that a chemical reaction has taken place by observing the change in volume and buoyancy of the air inside the balloon as it heats up.
What element is used in a hot air balloon?
Hot air balloons typically use propane gas as a fuel source to heat the air inside the balloon envelope, causing it to rise and lift the balloon off the ground.
What element is put in balloons so they float?
Helium is the element commonly used to fill balloons to make them float. It is lighter than air and creates lift within the balloon, causing it to rise.
What would heating the gas in an air balloon make the balloon rise?
Simple...hot air rises..
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 would heating the gas in a hot air balloon make the balloon rise?
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
Why would heating the gas in air balloon make balloon rise?
if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.
Why would heating the gas inan air balloon make the balloon rise?
because as you heat the gas, you cause the gas to expand on the container (whish is a balloon), this lowers the density, and a less dense fluid submersed in a denser fluid will rise, like an air bubble rises from underwater
Why would heating the gas in balloon make the balloon rise?
if you mean how the hot air in a hot air balloon makes it rise, its because hot air is less dense than cold air. when cold and hot air meet the cold air sinks thus making hot air left to rise.so when you put hot air in a balloon the air would rise. hope this helps.
Why would heating a hot air balloon make the balloon rise?
Heating the air inside the balloon makes it less dense than the surrounding air, causing it to become buoyant and rise. As the air inside the balloon is heated, it expands and its volume increases. This expansion pushes the surrounding air down, creating a lift force that allows the balloon to ascend.
Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?
He would heat it.
Why Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?
Heating the air makes less air take up the same space, so the air inside the balloon is lighter than the surrounding air. The pilot turns off the burner to help the balloon to maintain the current altitude or to descend.
Why would heating the gas in a air balloon make the balloon rise?
Heating the gas in the balloon makes it less dense, causing it to become lighter than the surrounding air. This creates a buoyant force that lifts the balloon upwards. As the gas cools, the balloon descends back to the ground.
Will a balloon rise if the air inside is hot?
The heating of the air through the use of a burner is what makes balloons rise.
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.
