FEMALE STUDENT: How can liquid exist below freezing? Why doesn't it freeze?MALE PROFESSOR: Well… when water becomes ice, the molecules bond together and they get sort of, uh, locked into place. They can't move around as much anymore. So each molecule is surrounded by other molecules...
1. Water is actually quite simple, but the way how the water molecule is formed gives water its unique properties.2. Water is a liquid at room temperature and has a relatively high frozen point.3. The nutrients in whatever falling into the ocean will quickly become available to other ...
For the H-bond-forming liquid ethylene glycol (EG) embedded in zeolites of different sizes and topologies one observes a sharp transition from a single-molecule dynamics (with an Arrhenius-type temperature dependence) to that of a liquid (with a temperature dependence of the mean relaxation rate...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
At a given temperature, the pressure exerted by a gas that is in equilibrium with a solid or liquid is called vapor pressure. It is also a measure of the substance to transform into its gaseous phase. In general, the vapor pressure increases as the tem...
The OH (O - H) group on the molecule is what makes it an alcohol. There are four types of bonds in this molecule: carbon-carbon (C - C) carbon-hydrogen (C - H) carbon-oxygen (C - O) oxygen-hydrogen (O - H) The chemical bonds between the atoms are shared pairs of electrons....
as the Universe is transparent to gravity all the way back to the beginning. When the Universe might have been a trillion to a quadrillion times hotter than the hottest place in the Universe today, neutrinos are likely to have behaved in just the way we require to ensure our survival. We...
“balls” represent hydrogen atoms. In (b), a representation of a water molecule’s molecular formula is presented. The letter “H” symbolically refers to the hydrogen atom, the number “2” refers to the number of hydrogen atoms in the molecule, and the letter “O” symbolically refers ...

They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubberier like slime! Picture the difference between wet spaghetti and leftover spaghetti the next day. As the slime forms the tangled molecule strands are much like the clump of ...
