In the case of hydrogen and oxygen gas, if you react them together one way you get liquid water (H2O). The reason we cannot breathe liquid water is because the oxygen used to make the water is bound to two hydrogen atoms, and we cannot breathe the resulting liquid. The oxygen is usele...
Methods:Two different modes of EVA were investigated in an experimental model of respiratory failure: intra-rectal oxygen O2gas ventilation (g-EVA) or liquid ventilation (l-EVA) with oxygenated perfluoro-carbon. After induction of type 1 respiratory failure, we analyzed the effectiveness of g-EVA ...

If they carry all of that oxygen with them from Earth to Mars, though, it will actually make the mission more difficult and more expensive. This is due to the mass and weight of the oxygen, as liquid oxygen is actually heavier than water. Thus, you'd ne...
The clear liquid is beeswax, a nutritionally rich animal wax that bees secrete. There are two types of beeswax: bleached and yellow. The significant elements of beeswax are esters (which make up 70%), free wax acids, and hydrocarbons. Beeswax has many skin benefits, including being completely...
Healthy plants produce oxygen for humans and animals to breathe. Volcanoes also remove heat from the earth’s interior (内部), which helps keep our planet cool. In recent years, a new benefit of volcanoes has surfaced. 20 Their measures involve using the heat beneath the earth’s surface ...
That episode of "30 Rock" whereLiz had to scarf down an entire Teamster subis accurate, but only because she couldn't give up the dipping sauce. Feel free to stop by the deli for a sandwich before getting on your flight, but leave the liquid dipping sauce behind (if it's over 3.4...
Most things have three states:solid,liquid and gas.We can change a solid into a liquid and liquid into a gas.It doesn't matter which of the three states a thing is in,it is still the same thing.Let's think about water to see how this works.Water is one of those things that ...
Maintain your electrolytes (电解质) and body liquid. Sports drinks can be used. Monitor your blood pressure and control it if necessary. Dropping blood pressure may be a serious sign of infection. Breathe in an oxygenrich environment. Quickly address any symptoms of infection. Be honest abou...
Water is made of two hydrogen atoms attached to an oxygen atom. This seems like pretty basic chemistry, so why don't we just smash them together and solve the world's water ills? Theoretically, this is possible, but it would be an extremely dangerous process, too. To create...
