Why does salt crystallize? Why is temperature an intensive property? Why is thermal stratification important? Why is the melting of ice not a chemical reaction? What is the reason for ice being less dense than water? What affects the melting point of fats?
Why does salt cause ice to melt? Why do molecular substances have relatively low melting points? Why does I_2 have a higher boiling point than F_2? Why is it important to add heat slowly and steadily when the temperature gets close to the melting point?
All salt is good, as long as the salt crystals are fine enough and dissolve easily. A lot can be said for different types of salt, some contain additives, some have other minerals next to the sodium chloride (NaCl) considered beneficial for you (like Celtic sea salt which is also lower ...
This binding action prevents the ice crystals from growing larger. And this is what prevents Notothenioids from freezing. Now, at that time, the waters the Notothenioids inhabited were still not freezing cold, so the protein didn't really make a difference as far as the fish's survival....
Salt has been used for hundreds of years as a preservative, and some food makers use it as a flavoring because it's cheaper. It's more expensive to use other herbs and spices to make food taste good better than to add salt. + + + Mary Ellen DiPaola, outpatient dietitian at the Univ...
To vary yourbuoyancy experiment,add salt to the water. Make the water look milky with salt. Because you won't want to fill a wading pool with salt water, you'll want to do this on a small scale, like an ice cube in a glass. ...
If Toxic Crystals Are So Bad, Why Do Some Recommend Them? Well, I really cannot say why some recommendations don’t give at least a fair warning, but I suppose that most who are recommending the crystals assume the danger is low.Sometimes it is…and sometimes it isn’t. ...
A lot of us at Zero like a mug of low-calorie bouillon at mealtimes to replace the ritual of food. We’ve also been known to chew on pink Himalayan salt crystals to give our teeth something to do. When You Shouldn’t Supplement with Sodium ...
23. Why does it walk on snow? The brittle ice crystals of snow oil, when one steps on them, ice crystals are compressed, ice crystals are destroyed, and the air is squeezed out. These processes have sounds. 24. Why understanding the oceans from space? Satellites make it possible for us...
it's worth noting thesalted water actually boils more quickly. That seems counter-intuitive, but you can easily test it yourself. Put two containers on a stove or hot plate to boil -- one with pure water and the other with 20% salt in water. Why does the salted water boil more quickl...
