Since hotter air is less dense than colder air, it becomes lighter than the surrounding air. Cold air filling a certain space has a certain mass. Since warmer air takes up more space, it takes less warm air to fill the same space, giving it less mass. There is less air there, so it has less of a mass, allowing it to float on top of the other air.
enough to make me hard
air is heavier than balloon, air rises
The volume of air increases on its heating hence the balloon rises on heating
Balloon is too roasting to be hot. Balloon is so much more blazing
-- Inflate the balloon with some substance that is less dense than air. OR -- Inflate the balloon with air, then heat it after it is sealed.
A gas of low density has the tendence to ascend.

Make the balloon capable of further expansion. That way as the balloon rises and the barometric pressure falls the balloon can expand and allow its internal gases to achieve a constantly decreasing density.
No. The volume of the helium will change as it expands the balloon due to the increase in temperature. The density of an element never changes. The reason for that is because density is just a fancy way of saying 'The atoms are this far apart' in the equation mass/volume = density.
because salt increases the density of water so, egg ascend to top
The hot air has a density under the density of cold air. And so up in the atmosphere.
Any gas that is more dense than air.Answer:It is a bit more complex than that - an air filled balloon would still fall because air has the density of air. In a normal inflated balloon the air in the balloon is compressed and has a density more than uncompressed air. If the "balloon" were a plastic bag wiith no air pressure above the pressure of the surrounding air, the balloon would still fall as the combined (average) density of the balloon/bag system is greater than the surrounding air. Even if the balloon were filled with a gas with a lower specific gravity than air the balloon wll fall if the compressed gas density excedes that of the surrounding air or if the combined (average) density of the balloon/bag or balloon system is greater than the surrounding air.
Heated gas has a lower density than environmental air.
Making cookies would constitute a chemical change.
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 :)
The density will make the difference between a fluffy cake and a hard cake.
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
