The cold water can cause heart attack due to severe vasoconstriction, [2] where the heart has to work harder to pump the same volume of blood throughout the arteries. For people with pre-existing cardiovascular disease , the additional workload can result in myocardial infarction and/or acute heart failure , which ultimately may lead to a ...
Argon-36, in the form of argon hydride ions, has been detected in interstellar medium associated with the Crab Nebula supernova; this was the first noble-gas molecule detected in outer space. [ 33 ] Solid argon hydride (Ar(H 2 ) 2 ) has the same crystal structure as the MgZn 2 Laves phase .
Here, you have to hold the ice as its disappearing, the airflow has to be positioned just right so the ice isn't occluded by mist and you have to be careful not to burn your fingertips on the super-cold tweezers! I never figured out how to avoid that last bit. :) Everything you see here is argon ice, it has been taken out of the glass cylinder.
A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines ...
Thursday's weather will feature an Arctic blast for the Midwest and Northeast and still more lake-effect snow for the Great Lakes. Cold air associated with a high-pressure area will move over the ...
A recent study concluded that people who predominantly sit at work have a 16% higher risk of mortality from all causes and a 34% higher risk of cardiovascular disease. These more sedentary ...
Argon dissolved in water causes the pH to rise to 8.0, [81] apparently by reducing the number of oxygen atoms available to bind protons. [82] With ice, argon forms a clathrate hydrate. Up to 0.6 GPa, the clathrate has a cubic structure. Between 0.7 and 1.1 GPa the clathrate has a tetragonal structure.
Colder temperatures, especially in winter months, won’t cause a common cold. But they can weaken your immune system, and colder, drier air can help respiratory viruses thrive.
