Why does ethanol made by fermentation have to be purified? How does water gets to the lungs and how can water be exhaled if it is liquid form? Why is 2-Methyl Propan-2-ol viscous and a solid at room temperature? Why are glucose and oxygen important in aerobic respiration?
Gasoline is made fromcrude oil. The crude oilpumped out of the groundis a black liquid calledpetroleum. This liquid contains hydrocarbons, and the carbon atoms in crude oil link together in chains of different lengths. It turns out that hydrocarbon molecules of different lengths have di...
A balloon filled with helium does not rise in the air indefinitely but halts after a certain height. Explain why?Buoyancy:An object submerged in the fluid will experience an upward force acting on it from the fluid. This force is called buoyancy force and...
In a chiral smectic C liquid crystal, a bend type deformation of the C-director induces a polarization charge. We have shown that due to the screening effect by impurity ions the free energy of the electrostatic interaction of the polari... Okano,Koji - 《Japanese Journal of Applied Physics...
Yes!There can actually be a whole lot of water vapor in the air webreathe. The word for how much water vapor there is in the air is "humidity". ... And when the air can't hold as much water vapor as it actually has, some of the water will condense into a liquid form. ...
Mesothelial cells form a monolayer of specialised pavement-like cells that line the body's serous cavities and internal organs. The primary function of this layer, termed the mesothelium, is toprovide a slippery, non-adhesive and protective surface. ...
A s the silicon analog of graphene, free-standing silicene was predicted to have a Dirac cone in the band structure, and its electrons near the Fermi level follow the massless Dirac equation just like graphene1–3, which will lead to many unique properties such as ultra-high carrier mobility...
MALE PROFESSOR: Good...all evidence of water in liquid form—large quantities of it. Now remember when we talked about star formation, we said that as a star ages, it becomes brighter. Right? Hydrogen turns into helium, which releases energy. So our standard model of star formation ...
What is the element whose -1 ion would have the same electron configuration as krypton? What is the element whose +2 cation has the same electronic configuration as krypton? Bromine is a highly reactive liquid while krypton is an inert gas. Explain this difference based on their electron confi...
Why do scientists believe that the Earth's inner core is solid and that the outer core is liquid? Why can't a white dwarf have a mass greater than 1.4M? Why is a larger nucleus generally less stable than a smaller nucleus? Besides the sun, are there any terrestrially based exam...
