Air is a mixture. A mixture of compounds (e.g. carbon dioxide, water vapor, methane, nitrogen oxides, sulfur dioxide, carbon monoxide), elements (e.g. nitrogen, oxygen, argon, ozone, Mercury vapor), and various microscopic particulates (e.g. dust, pollen, spores, water droplets, bacteria, viruses).

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 gas is inside an air balloon?
Helium is usually the gas inside an air balloon. It is lighter than air and helps the balloon float.
Is a hot air balloon a chemical change?
No, a hot air balloon involves physical changes such as heating and expanding the air inside the balloon, without involving any chemical reactions.
This type of compound is usually formed when you burn an element in air?
Oxides are the type of compound that is typically formed when an element is burned in air. Oxides are compounds composed of an element combined with oxygen.
What happens when liquid nitrogen is poured on balloon?
When liquid nitrogen is poured on a balloon, the air inside the balloon quickly cools and contracts, causing the balloon to deflate. The extreme cold of the liquid nitrogen causes the gas particles inside the balloon to lose energy and move closer together, resulting in a decrease in pressure that makes the balloon shrink.
Is an air inside a balloon a pure substance?
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
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.
When you heat the air inside a hot air balloon, it rises. Why does this occur?
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
When is the density of the air inside a hot air balloon greatest?
The density of the air inside a hot air balloon is greatest when the air inside is coolest. 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 does the volume in a hot air balloon change?
The volume of a hot air balloon increases as the air inside the balloon expands when it is heated. As the balloon ascends and the air temperature decreases, the volume of the air inside the balloon decreases as well. The pilot can control the altitude of the balloon by controlling the temperature of the air inside.
Is air inside a balloon a element?
In a helium balloon- one that floats and rises to the ceiling it is elemental helium that is used to inflate the balloon. If you just blow into a balloon to inflate it then it is air inside the balloon which is a mixture of gases, principally nitrogen and oxygen (both elements). There are also other gases that are chemical compounds such as carbon dioxide.
In a hot air balloon air is heated by a flame Explain how this enables the balloon to float?
Heating the air inside the balloon makes it less dense than the surrounding air, causing the balloon to float upwards. As the air inside the balloon cools, it becomes denser and the balloon descends. The pilot can control the altitude by adjusting the temperature of the air inside the balloon.
What creates pressure inside of a balloon?
The pressure inside a balloon is created by the air molecules contained within the balloon pushing against the walls of the balloon. As more air is blown into the balloon, the number of air molecules increases, leading to a higher pressure inside the balloon.
What happens to air in a balloon?
When air is blown into a balloon, it fills the space inside. The pressure of the air increases, causing the balloon to expand. If the balloon is sealed, the air inside remains trapped, making the balloon float or hover depending on the amount of air inside.
When you heat the air inside a hot air balloon it rises. Why does this occur?
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
When the balloon is up in the air the burner is turned off and the balloon drifts along with the wind What will eventually happen to the air inside the balloon?
As the balloon cools down, the air inside will also cool. This will cause the air pressure inside the balloon to decrease, potentially leading to the balloon descending back to the ground due to the decreased pressure.
What happens if the volume of the air inside balloon increases while the mass of the air stays the same?
If the volume of the air inside a balloon increases while the mass remains constant, the density of the air inside the balloon will decrease. This means that the air inside the balloon will become less dense.
