Cool Air! As the heated air rises the heated air starts getting cool. This is because the higher the air is the colder it gets. Then the heated air will be replaced with cold air. As the cold air then comes down near the ground the cool air will become heated because of the sun. Heated Air - Cool Air - Cold Air And On And On It Goes
Solids and liquids are composed of atoms or molecules that are held together by various kinds of chemical bonds, whereas gases are composed of independently moving particles that are not held together, therefore they are free to expand.
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
A reaction of oxydation with the oxygen from air.

Heated air, like what you breath.
They have be heated to liquid form first, and from that they must be heated more to be able to evaporate into the air and become a gas.
all gases. The volume of a gas is directly proportional to the temperature, and inversely proportional to pressure. Maybe you mean air, but air is a mixture of gases
The two types of air balloons are * One is lifted using heated gases. * Another one is lifted using unheated gases.
its pressure will increase if it is placed in a fixed container, or it will expand if it is free to do so
Hot air balloons are simply that, hot air. Air inside the balloon or envelope is heated, this becomes less dense than the surrounding air therefore creating buoyancy.
