The process of thermal decomposition of organic materials (carbon based materials) at very high temperature and absence of oxygen is known as pyrolysis.
The temperature for such process is generally 430 °C or 800 °F. This causes simultaneous change in physical phase and chemical composition of the organic material. The process is irreversible in nature.
The resultant products mostly have more useful properties than the original one. Thus, to bring the greater value to the common organic material and waste, the idea of pyrolysis is important.
Explanation:
8% 9:30 pm The binding energy B is the energy associated with the mass difference between the Z protons and N neutrons considered separately and the nucleons bound together (Z+N) in a nucleus of mass M. The formula is B = (Zm, + Nm, - M)c², where mp and m, are the proton and neutron masses and c is the speed of light.
Li + e- ===> Li+
it looses its valence electron to form a uni-positive ion
Carbon-14 and Uranium-238 have something we call a half live, which is basically a known time period for it to change half of its C-14 or U-238 radioactively decay. Since we know how long that is 5730 years for Carbon-14 for half a sample to deteriorate, than we can figure out how old it is.
