Helium is the result of many radioactive disintegrations; alpha-disintegration of uranium natural isotopes, for example, release helium.
sorialso sporangiaSori are the structures on the underside of fronds in which the spores of ferns are produced.
Flexibility and brittleness are properties of solids. Because of its very unusual quantum properties (compared to nearly all other elements - hydrogen is weird too) flexibility and brittleness may not really apply to solid helium. Helium CAN be turned into a solid - but it requires elevated pressures and REAAALLLY low temperatures. Because of quantum effects, it can remain liquid all the way to absolute zero at normal pressures. To get a solid requires pressures above about 2.5 MPa (25 bar) and temperatures down around 1 Kelvin. In theory you could get it solidify at room temperature if you could get it up to a pressure of 114,000 atmospheres (1,675,338 psi) but well before those pressures helium tends to diffuse into whatever solid forms the walls of its container - causing embrittlement, leading to fractures - aaaaannnnnnddddd - POW! Suffice it to say that at such extreme temperatures flexibility is difficult to measure. At least one experiment found no penetration of a probe 0.6-mm in diameter until the force exerted exceeded 330 dyne - at which point it gradually penetrated the sample at a rate of about 3 µm/sec. As soon as the probe was withdrawn, the indentation "healed" - kind of like rubber rebounding after compression, but in this case it more like the helium flowing back into the depression. Apparently solid helium doesn't so much flex as flow. Brittleness usually is defined as the response to stresses. As already noted, it sort of flows when subject to compressive stress. Solid helium als behaves strangely under shear stresses. It can be a "supersolid", i.e. a solid exhibiting superfluid characteristics like zero viscosity flow, consequently when placed under shear stress it may decouple from the the shearing surface making any measurements meaningless.

Your gas bill will likely be highest during the winter season when heating demands are at their peak. Cold temperatures require more energy to maintain a comfortable indoor environment, leading to increased gas consumption. Additionally, if your home is not well-insulated, the gas bill can be further elevated due to heat loss.
Gas giants like Jupiter and Saturn do not have a solid surface to land on because they are composed mostly of gas and liquid. Their outer layers consist of dense clouds of gas that gradually transition to liquid deeper within the planet. Attempting to land on a gas giant would be like trying to land on a thick, stormy atmosphere.
helium's valency is zero as id does not combine with other elements
while scene the only real liger is a artificially bread science experiment id say pixies and faeries.
put some gas in the car
id Software
Yes it can. Id gave me really bad gas but it is not a main side effect.
Most cerebrospinal fluid (CSF) is produced within the lateral ventricles of the brain.
id say the exhaust system or gas tank
Stepinie Meyer produced Twilight, New Moon,eclipse and breaking dawn [[sorry idk id i spelt her name right]]
Id is an inert gas atmoshere containing carbon dioxide.
if you hav fuel injection, id say its in the gas tank, if not follow gas line from the carb.
Total number of cards by type produced at your site
Id believe so.
