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.
The 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.
As the particles inside the balloon are heated, particles spread farther apart and begin to move faster, and therefore the collisions become more violent. 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.
Heating the air molecules inside the balloon makes them move faster and spread out, so that the hot air becomes less dense than the surrounding air, and the balloon is then able to float, or rise.
Heating the balloon cause the air inside to gain heat and as hot air rises,the balloon rise.
Hot air, or any gas, spreads the moleclues out, which makes it lighter, thus it will rise.
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 :)
Hydrogen atoms are less dense than the air, therefore hydrogen balloon rises in air.
its electrons in its outer shells become excited and rise to higher energy levels then as the electrons reach their highest point they fall back to their original energy level this releases photons which we see as light, depending on how high the electrons rise and fall determines the wavelength of the photon and as a result the colour
Rising until 0 °C, then melting, then rising again while continiously heating
A substitute for ammonia-bicarbonate would be baking powder. Ammonia-bicarbonate is used with or without yeast in the baking industry to make dough rise.
Simple...hot air rises..
The volume of air increases on its heating hence the balloon rises on heating
Hot air expands. When it expands, it becomes less dense and rises.
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.
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.
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
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.

Hot air rises. By heating the cool air in the balloon using a propane heater, heats the air and makes the balloon rise
He would heat it.
To make air lighter you would increase the heat inside the balloon, making it less dense, causing it to rise.
The heating of the air through the use of a burner is what makes balloons rise.
