Webtemperature (K) = temperature (°C) + 273.15. Thus, the melting point of water is = 0°C = 273.15 K and the boiling point of water is = 100°C = 373.15 K. On the Fahrenheit scale (°F), the melting point of water = 32°F while the boiling point = 212°F. Therefore the degree size is different on the Fahrenheit scale with 180 Fahrenheit degrees ...

Web1. Photochemical dissociation of oxygen results in the production of two oxygen atoms, one in the ground state and one in the excited state. O2 hv → → hv O→O*. The maximum wavelength () needed for this is 174 nm. If the excitation energy O→O* is 3.15 x 10-19 J. How much energy in kJ mole-1 is needed for the dissociation of one mole of ... Web4 apr. 2013 · As you go down any group, there are extra electron shells (for example Lithium has 2 shells, Francium has 7) which cause electron shielding. Because the force of attraction must extend further and through these shells to the outermost shell, the force becomes less so there is less strong bonding occuring. road bike front derailleur
