What else can I help you with?
When you put a balloon in a cold room then in a worm room does its density change?
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.
Is Density of helium balloon is greater or less than air?
The density of a helium balloon is less than that of the surrounding air. This is why helium balloons float in the air. Helium is lighter than the nitrogen and oxygen that make up the majority of Earth's atmosphere, so it provides buoyancy for the balloon.
How do particles make a hot air balloon work?
Particles in the air are heated by a burner in the hot air balloon, causing them to expand and become less dense. This creates a pressure difference between the inside and outside of the balloon, allowing it to rise and float in the atmosphere.
Can anyone suggest a test for hydrogen gas other than burning splint?
Fill a balloon with the gas and see if it is lighter than air (only Helium and Hydrogen will make a balloon float...) Calculate the density of the gas (mass/volume)
Is burning a balloon a physical or chemical change?
When thinking of a balloon, it's best to think of two different chemical compounds that do not mix, the balloon itself and air. What makes the balloon pop is that the pressure of the air exceeds the force of the chemical bonds of the balloon. In order for a chemical reaction to take place, you need to start off with one set of chemicals that become a new set of chemicals.However, when a balloon pops, no new chemicals are created. All that happens is that the electron bonds of the compound we know of as the balloon break.
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 :)
When is the density of a hot air balloon the greatest?
The density of a hot air balloon is the greatest when the air inside the balloon is at its maximum temperature. As the air inside the balloon is heated, it expands and becomes less dense compared to the surrounding air, causing the balloon to rise.
How would you make a balloon get the maximum elevation it can get?
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.
When you put a balloon in a cold room then in a worm room does its density change?
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.
Why does a change in the density of the air make the hot air balloon ascend?
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.
How does a hot air baloons fly?
Hot air balloons fly by heating the air within the balloon envelope, which causes it to become less dense than the surrounding air. This difference in density creates lift, allowing the balloon to rise. By controlling the temperature of the air inside the balloon, the pilot can make the balloon ascend or descend.
How does adding salt to water make an egg float?
because salt increases the density of water so, egg ascend to top
How does heilum make a balloon float?
When helium is added to a balloon, it decreases the overall density of the balloon compared to the surrounding air. This causes the balloon to float because the buoyant force exerted by the helium is greater than the force of gravity acting on the balloon. This buoyant force allows the balloon to rise in the air.
How would you raise a hot air balloon above some trees?
To raise a hot air balloon above trees, you would need to increase the heat in the balloon by firing up the burner. The hot air will make the balloon lighter than the surrounding air, causing it to ascend. Piloting the balloon to catch different wind currents can also help in maneuvering it safely above the trees.
Why would heating the gas in air balloon make the balloon rise?
Heating the gas in the balloon causes it to expand and become less dense than the surrounding air. This lower density gas creates a buoyant force greater than the weight of the now lighter balloon, causing it to rise.
What gas put in a balloon would make it fall?
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.
What do you blow up a balloon to make it fly?
Helium gas is typically used to fill balloons to make them float or fly. Helium is lighter than air, so it causes the balloon to rise due to the difference in density between the helium gas inside the balloon and the surrounding air.
