Helium is a gas that is less dense than air. This is why a balloon filled with helium rises when released.
No everything is layered in density, water is much more dense than air. The whole planet is organized based on density with the core being the most dense and the exosphere being the least dense.
Helium and neon are less dense than air; argon, krypton, xenon and radon are denser than 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.
Warm air is less dense than cold air because the air molecules in warm air have more energy and are therefore more spread out. This results in fewer air molecules in a given volume, leading to lower air density.
Helium gas is found in balloons that rise to the ceiling. This gas is less dense than air, causing the balloon to float upward.
Ammonia is less dense than air at room temperature and pressure. This is why ammonia gas rises in air.
helium is a gas less dense than 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
Because hydrogen gas is less dense than air(mostly nitrogen and oxygen), and the less dense gas flows to go above the more dense(and escape the atmosphere).
Bromine gas is denser than air. At room temperature and pressure, bromine gas is about 7 times denser than 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.
Any gas which is less dense than air. Even hot air will suffice.
Warm air is less dense (lighter) than cold air..that is why warm air rises and cold air settles
i think its hellium helium
0they float because they are less dense than the air surrounding it
Because it is a safe gas that is less dense than air, thus balloons float in air
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.
