Yes ammonia is less dense than air
Warm air is less dense than cooler air.
cold air has higher density, by hot air is opposite
No, ammonia is less dense than air.
It is more dense.
Air, oil, ice. One of the few substances that its solid form is less dense
Ice Air is less dense than water, so water sinks below air. A rock is more dense than water, so it sinks in water and air. And helium, which is less dense than air, rises in air and in water.
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
Yes ammonia is less dense than air
Hot air balloons heat up contained air so that the density of it becomes significantly less than the outside air and thus the container (balloon) will rise of float in the surrounding air until the density difference is null. Buoyancy is just that, less dense substances floating or rising in more dense substances. The other approach is saying more dense substances sink in less dense substance.
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.

Warm air is less dense than cooler air.
Warm air is less dense then cold air. But moist air is actually less dense than dry air because water vapor has a lower molecular weight than the oxygen and nitrogen that make up most of the atmosphere.
Helium and neon are less dense than air; argon, krypton, xenon and radon are denser than air.
Helium is a gas that is less dense than air. This is why a balloon filled with helium rises when released.
Air is more buoyant than water because air is less dense than water, and everything the thing that is less dense is always more buoyant than what is more dense than it.
