Symptoms and effects will vary depending upon the length of the addiction, the amount of drug used, and the frequency the narcotic was abused. Withdrawal from narcotics should always be done under the close supervision of medical personnel.
A: Helium balloons float because they are less dense than the surrounding air, which causes them to rise. Gravity acts on helium balloons the same way it does on the surrounding air; it has no effect on whether the balloon floats or not. It all comes down to relative densities. Continue Reading
Thus even the air inside would be heavier than the equivalent mass of uncompressed air outside. Therefore it also makes sense to use a material that does not stretch. In order to make the balloon float, we must fill it with a gas that is not as dense as the air that surrounds it. Helium is ideal because the molecules are spread out much more than the molecules in the surrounding air -- and is therefore lighter (fewer molecules means less weight for a given mass of gas). Moreover, the material used in helium-filled balloons (party balloons) is wafer-thin and extremely light.
