Q. Scientists have unveiled the unexpected behaviour of which molecules?- Published on 26 Apr 16a. Water
b. Gas
c. Solid
d. None of the above
ANSWER: Water
Scientists including an Indian origin researcher have unveiled unique and unexpected behavior of water molecules not matched by known gas, liquid or solid states.
- A new tunnelling state of water molecules confined in hexagonal ultra small channels- 5 angstrom across- of the mineral beryl
- Agostrom is 110 billionth of a metre and individual atoms are associated with one angstrom in diameter
- This demonstrates features of water under ultra confinement in rocks, cell walls and soil.
- The neutron scattering and computation chemistry experiments showed that in the tunnelling state, water molecules are delocalised along a ring so double top like shape is assumed.
- First principle stimulation show that tunnelling behaviour is coupled to the vibrational dynamics of the beryl structure
- Kinetic energy of water protons obtained from the neutron experiment is a measure of their motion at absolute zero temperature and around 30 percent less than in built liquid or solid water.
