Actually it is heavier than air. And it will sink much like co2 does in air
It weighs less than air. Density of air is 1.2 kg/m3, density of methane is 0.72 kg/m3 (at standard temperature and pressure). Natural gas is mostly methane but does contain small amounts of heavier hydrocarbons, ethane, propane, and butane, but the mean density is still less than that of air.
because there is less gravity in water
Cold air falls and warm air rises. Warmer air rises above cooler air because it is less dense. The particles vibrate and move further apart so the molecules that compose the air are more spread out, causing the warm air mass to weigh less than the cool air.ass
Hot air balloons get their buoyancy from hot air created by a propane burner at the base of the balloon. Hot air is less dense than cold air and so weighs less. When the cold air that is displaced weighs more than the balloon, the balloon will rise. The balloons weight is controlled by turning the burner on and off when needed. The hot air is less dense than the outside air and so the balloon is squeezed upwards by the surrounding air. The air becomes less dense as more heat is applied, particles separate more and more when heat is applied. The more heat is applied the further apart and less dense the particles become.
Since weight is the measure of an object's gravitational pull, the compressed air does not weigh more. The difference is in the density of the air. A tank filled with compressed air will weigh more than a tank that is filled with air at normal atmospheric pressure.

Hot air is less dense than cooler air. This makes it weigh less then the surrounding air so it rises.
If the air in the balloon is cooler than the air around it, it will sink. Hot air balloons go up because they weigh less than the air around them.
A hot air balloon is inflated with air and then heated by a propane fueled burner. The balloon contains air andthe products of combustion of propane, namely carbon dioxide, which is heavier than air, and steam, which is much lighter than air.
Need more info. Either the volume or density of the stone. From the info given all we know is that it will weigh less in the water than in the air.

Appended is a list of gases with their specific gravities. The specific gravity of a gas is a comparison of its density with that of air at the same temperature and pressure. Gases with a Specific Gravity (SG) less than1 are lighter than air.
The air inside the balloon is heated with a propane burner. As air is warmed, it becomes less dense (lighter) and rises.
No, air has a density of 1.225 g/l @ 15°C. and Standard Atmospheric Pressure while butane is 2.52 g/l. Butane is more than twice as heavy as air!
Air
Yes, because the helium is buoyant relative to the atmosphere at ground level. However, the helium would have more mass than the bottle with no air.
