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).
Imagine inhaling to blow in a balloon. You will take in air, hold it in your mouth and blow it into the balloon. Some of it will be the carbon dioxide you were exhaling but most of it will be the air you just breathed in. So, the gas inside the balloon will be a mixture, that is, air.
That depends on the element you are burning.
Only a hot mixture of the same gases that are in the air you breathe.
Liquid nitrogen has a low temperature, and that obviously decreases the volume of the air inside the balloon. The balloon shrinks
Element: oxygen, potassium Compound: sodium chloride, potassium dichromate Mixture: air, orange juice
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.
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
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.
the air inside the balloon has more kinetic energy
No, I am sorry, but there is no helium inside a hot-air balloon. Instead, there is hot air.
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
No. Air or helium goes inside the balloon.
For a balloon that is sealed and not full the volume of air inside the balloon will increase as it is heated. This is not however how hot air balloons work. A hot air balloon is essentially a fixed volume when it is inflated. If the air inside the balloon is heated the air inside becomes less dense so some of the air exits the balloon via the mouth of the balloon. As the air inside the balloon cools it becomes more dense so some air is ingested via the mouth of the balloon to keep it full. With each heating and cooling cycle, the pressure inside the balloon remains constant, the volume of the balloon remains constant but there is this movement of air out of and back into the balloon. P=VT Poop
air is a compound and also an element. its a compound because it has carbon dioxide (CO2) and its an element because it has oxygen (O2).
The hot air inside the balloon expands, making the hot air balloon fly.
A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.
Heating causes the air inside the balloon to expand. Some of the warm air leaves through the bottom opening of the balloon, keeping the pressure constant.
