could be alone in the universe. The first reason Earth was able to become this welcoming blue sphere is because it's at just the right distance from the Sun, in a narrow zone not too hot and not too cold, where the temperatures are compatible with liquid water and life....
It isn't too hard to imagine that if we add heat energy to a gas we raise the temperature by causing its molecules to move around more vigorously which in turn makes it want to expand,for each madly careening molecule is knocking its neighbors farthe
But if salt needs to interact with liquid water, how does it do anything when temperatures are stubbornly below freezing, and water should already be in the form of ice? That’s where cars help clear their own ...
and when those bands are broken that potential energy transformed to other types of energy like heat or light Kinetic energy is the energy of motion, and molecules(分子)are always moving, They're not necessarily going somewhere (though they could be), but they are vibrating(震动), stretching...
The physical properties of a material are the properties that are used to define it. These properties arise from the orientation of the molecules in space as well as the relative interaction occurring between them. Answer and Explanation:...
Why isn't there a gravitational pull on fire? Explain why the noble gases tend to be monatomic rather than diatomic. Why does the temperature of gas increase when it is suddenly compressed? Why do hot molecules move faster than cold molecules? Why are heavier elements not much larger than ...
The temperatures I pull the turkey out of the oven at and when it is ready to cut are different. Proteins, will continue to cook even after you have removed them from the heat source, related to the molecules vibrating or moving rapidly. 4 After you finish enjoying your feast, the ...
Carboxylic acids are found in sebum, the oily substance that creates a barrier and helps protect our skin. “The carboxylic acids are large molecules,” Vosshall explained. “They’re not that smelly by themselves,” she said. But beneficial bacteria on the skin chew on these acids that ...
which smell like rotten eggs.And molecules with very different structures can smell similar.Most strikingly, some molecules can smell different — to animals, if not necessarily to humans — simply because they contain different isotopes (atoms that are chemically identical but have a different mass...
into the deeper structure of the universe. In a flight of fancy I even see the parallel between how the Bible depicts the creation of humanity – the merging of breath/spirit and matter — and what words themselves are – the merging of spirit/thought and the vibrating molecules all around...
