Does helium have weight

Answer 1

Helium (as with Hydrogen) is a very light gas, too light to be retained by Earths gravity. It therefore escapes our atmosphere. There will be present in traces due to chemical reactions and other human activity going on at the Earths surface, but none in appreciable amounts.

Answer 2

Gravity has the same identical effect on helium that it has on anything and everything else.
It causes a pair of equal forces between the center of the Earth and the center of a
jar of helium. The forces are equal in both directions, and have a strength that's
proportional to the product of the Earth's mass and the jar of helium's mass, and
inversely proportional to the square of the distance between their centers.

Gravity is also actually responsible for the additional, upward, buoyant force on the
helium, just like it is in the case of a hot-air balloon or a Basketball under water.
If the helium is submerged in a fluid, like for example water or air, then there's an
extra upward force on it, equal to the weight of the fluid that it displaces.

Answer 3

Yes helium does have weight. 1,000 liters (1 cubic meter) of helium. temperature and pressure weighs about 6.3 ounces.

Answer 4

Yes, all matter is affected by gravity.

.

Helium is more buoyant than air, and therefore helium floats above air, just as wood floats above water.

Answer 5

Helium can change the timbre of human voice.
