Researchers believe this trehalose molecule not only replaces water, but also in some cases can physically constrain the critter’s remaining water molecules, keeping them from rapidly expanding when faced with hot and cold temperatures. This is important, because expanding water...
Why do objects float in liquids denser than themselves? Why are Cepheid variable stars good distance indicators? What about supernovae? Why does the potential energy of molecules of the system increase when the distance between them increases? Why are the shells visible ...
means oil molecules are “repelled” from the surface. To be completely accurate, molecules are not repelled, rather there is a complete lack of any attraction. Teflon™ Coatings in Semiconductor Manufacturing PFA topcoats are also popular for semiconductor factory applications because of their ver...
This is because few people regularly consume the main dietary sources of DHA and EPA — cold-water fatty fish such as salmon, herring, mackerel, halibut, sardines, and bluefin tuna. This chart shows the DHA and EPA content of the most commonly eaten seafood items in the United States. DHA...
Green tea is one of the most well-known superfoods in the world, and it’s famous for more than just its great taste and long-standing traditional history. Drinking two or more cups of green tea per day can prevent sickness, help you heal if you do get sick, and even he...
When pure water is kept at its freezing point, the number of molecules breaking their bonds from the solid state and entering the liquid state is equal to the number undergoing the reverse process. Adding salt to the mixture reduces the concentration of water molecules in the liquid state, slo...
roadside muck into taffy. But since it does lower the freezing point of water, ice would melt, as long as the outside temperature isn't too cold. The reason this happens is that any solute dissolved in water interferes with the ability of the water molecules to coalesce into a solid ...
How do fabrics dry? Liquid water consists of numerous water molecules attracted to one another by cohesive forces. These molecules are in constant motion. The average rate of motion reflects the water temperature. The rate of motion for individual molecules in water will range from high to low....
Cats thrive on a protein-rich diet, unlike humans, who derive energy from carbohydrates. Proteins are complex molecules, and the body takes longer to break them down. Your cat might need heat from other sources, like the sun, to keep itself warm in the meantime. ...
By nature, infected tissues characteristically have a lower (more acidic) pH. And at these lower levels, a lower percentage of molecules will be in their lipid-soluble form, thus inhibiting the anesthetic’s effectiveness. This same kind of low-pH environment is also associated with tissues that...
