If a balloon is filled with a substance that's less dense than air ... such as helium, hydrogen, steam, or warmer air ... then the balloon is less dense than air.
Heat makes air less dense and therefore rise.
Air becomes more or less dense relative to its temperature. Cold air is denser than warm. Since the equatorial region is tropical, the air will be warmer and less dense.
The heat from condensation makes the rising air warmer and stay less dense than the air around it.
When dense,cold air meets less dense,warmer air, the warm air is pushed up

Because it is less dense than the material that makes up the earth's crust, but more dense than the material that makes up the air.
When an inflated balloon is released, the air inside it is less dense than the surrounding air, causing it to float upwards. This is due to the principle of buoyancy, where objects that are less dense than the air around them will float. The air trapped in the balloon makes it less dense, allowing it to rise.
its has more pressure

Ammonia is less dense than air at room temperature and pressure. This is why ammonia gas rises in air.
Yes. By definition, most gases are less dense than most solids. i can't think of a counter example. Plus, the gas inside a hot air balloon is superheated to make it even less dense, as heating things makes them less dense
