The balloon
A balloon is less dense than an apple because it is filled with air, which has a much lower density than the solid matter that makes up an apple.
No, hot air balloons are kept up in the air by buoyancy, the same thing that keeps helium balloons up in the air, or that keeps ships afloat. The hot air in the balloon is less dense than the surrounding air, so the balloon weighs less than the air it displaces, at least while the balloon is rising.
No, the balloon with the least amount of air will not necessarily go out faster. Factors such as wind speed and direction, temperature, and weight of the balloon will also affect the rate at which the balloon goes out.
Hydrogen gas is considered the least dense element. It is less dense than air, which is why it is often used in balloons.
The least dense liquid is found at the bottom of the graduated cylinder, because the less dense it is, the farther it will go down in th graduated cylinder.

No. In fact it is the most dense planet. The least dense is Saturn.
Helium has the least density among the substances listed. It is a very light gas and is less dense than air, oxygen, ammonia, and chloride.
it is least expected in religious fortresses
One could say that the atmosphere is the least dense, but of the surface the crust is the least dense.
Helium is the least dense element at normal conditions.
'Least' is a comparison word. Compared to iron and lead yes cotton is least dense. Compares to oxygen gas and hydrogen gas, no it is not least dense.
When heated, gases typically expand and become less dense. So, a gas would be least dense when heated.
Saturn is the least dense planet in our solar system.
The exosphere is the least dense part of the earth's atmosphere.
An inflated hot-air balloon has much more mass, but is much less dense, than a 5-pound bar-bell. As a matter of fact, so is an aircraft carrier ... it floats, but the bar-bell sinks.
