[pure-silver] Re: Basic Chemistry

Chaps
I think the problem is one of basic physics not basic chemistry.  
Further to that I suggest the solution to the equation (ideally expressed in 
British Thermal Units rather than these strange continental values) would hold 
true only in laboratory conditions.  Physics is a lot like economics in that 
regard - many a good model is let down by the reality.
Rather than factoring in all the environmental variables, why not simply place 
the containers holding solutions A and B in bath C filled with water at about 
70F, equip bath C with an aquarium heater set to 70F, and turn it on an hour or 
2 in advance?

  Is it not also true that 1 degK = 1/100th of freezing to boiling ?  If so 
then the degK scale matches the degC scale.  I agree there is nothing special 
about that scale, but they do match.  So when concerting degK to degC, you only 
need to offset by 273.15, there is no scaling involved.  When converting degK 
to degF you must apply an offset and a scale.

      Note that I said "relative to absolute zero".  DegC IS only offset 
relative to 0degK, whereas degF is scaled AND offset relative to 0degK.



    Round not conceded.

    Both are scaled. Both are offset.

    At absolute zero the temperature is 0.00 in both
    the Kelvin and Rankine scales

    Offset:
    0 Centigrade = 273 Kelvin  or Absolute zero = -273C
    0 Fahrenheit = 476 Rankine or Absolute zero = -476F

    Scale:
    1 degree centigrade is 1/100 of freezing to boiling
    1 degree Fahrenheit 1/180 of freezing to boiling

    There is nothing special about either scale.
