Why would heating a gas in the air balloon make the balloon rise?

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.

Heating a gas in an air balloon makes the gas molecules move faster and spread out, decreasing the density of the gas inside the balloon. This lower density gas is lighter than the surrounding air and creates a buoyant force that causes the balloon to rise.

∙ 13y agoThe ability of the gas to make an air balloon float in air is determined by how less dense the gas is compared to air. When this gas is heated, it expands. When volume increases due to the expansion, the density of the gas decreases. This makes the balloon rise up farther.

And once there is a high amount of kinetic energy, movement is created and the balloon rises. Now, if the air inside a balloon was cooled, then it would somewhat deflate and it would not float as well, because the particles inside it become slower and closer together, and it would descend to the ground.

What gas can make a balloon float Is it hydrogen or Nitrogen or Argon or Chlorine?
Hydrogen gas can make a balloon float. This is because hydrogen is lighter than air and provides buoyancy to the balloon, causing it to rise. Nitrogen, Argon, and Chlorine are heavier than air and would not make a balloon float.
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.
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 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 is a chemical reaction that happens when a hot air balloon flies?
When a hot air balloon flies, the burner at the base of the balloon ignites propane to produce a chemical reaction that converts the propane into carbon dioxide and water vapor. This reaction releases heat, which warms the air inside the balloon, causing it to rise and lift the balloon.
What would heating the gas in an air balloon make the balloon rise?
Simple...hot air rises..
The air in hot air balloon is heated to make the balloon rise?
The volume of air increases on its heating hence the balloon rises on heating
Why would heating a hot air balloon make the balloon rise?
Hot air expands. When it expands, it becomes less dense and rises.
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 a air balloon make the balloon rise?
Hot air rises more quickly than cold air, so when you heat the air inside the balloon, it cant escape, so it pushes the balloon up.
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 the gas in air balloon make balloon rise?
Heating the gas inside the balloon causes it to expand and become less dense than the surrounding air. This creates a buoyant force greater than the weight of the balloon and its contents, causing the balloon to rise.
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
Would a hot air balloon pilot heat or cool the air in the balloon to make it rise?
He would heat it.
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.
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.
