About 2 minutes, the same as you would last not breathing oxygen.
An environment of helium could be fatal if it excluded oxygen to the degree that humans would be suffocated. Those squeaky voices in cartoons are often created by people breathing helium before speaking. However, they don't breathe helium for extended periods.
No, helium is toxic to your lungs and can kill you if you breathe it long enough, or you could have severe lung damage done to you.
The atmosphere is Jupiter is mainly composed of hydrogen (~90%) and helium (~10%). Since there is absolutely no oxygen, you would quickly suffocate if you were to attempt to breathe in the air (assuming, of course, that the atmospheric pressure and temperature didn't kill you first).
Yes, but you would die for sure. The combustion reaction would take all the oxigen and you will breathe carbon dioxide/carbon monoxide and that would kill you.
Every day, you breathe nitrogen and oxygen along with many other gases. Helium is inert and poses no threat at all except if you breathe only helium and you deprive yourself of oxygen. In theory, any gas can be breathed in small concentrations since the concentration is what determines hazardous effects. Even Oxygen can kill you if it is in too high of a concentration.
They do kill by sucking them in the sand. people wouldn't breathe
air can't kill you unless you breathe it in from a cigarette lots or breathe in carbon dioxide.
why would you drink any ink? and no it cannot kill you only if you are an idiot that drinks a whole bunch.
it will kill the person close to you
If in fact, the water we drink and the air we breathe both kill us over time, then there would be scientific proof and many different life forms would be extinct.
Yes, if we breathe too much of it.
It would take a dangerous amount of helium to potentially cause harm or death to a person. Inhaling concentrated helium can displace oxygen in the lungs, leading to asphyxiation, but the exact amount needed would vary based on individual factors. It's important to never intentionally inhale helium as it can be extremely harmful.
