| '''Kopp's law''' can refer to either of two relationships discovered by the German chemist [[Hermann Franz Moritz Kopp]] (1817–1892).
| |
| | |
| #Kopp found "that the molecular heat capacity of a solid compound is the sum of the atomic heat capacities of the elements composing it; the elements having atomic heat capacities lower than those required by the law of Dulong and Petit retain these lower values in their compounds."<ref>See page 96 of {{cite book | title = Physical Chemistry for Colleges | author = Millard, Earl Bowman | year = 1921 | publisher = McGraw-Hill| location = New York | url = http://books.google.com/?id=oYE6AAAAMAAJ&pg=PA96&dq=Kopp%27s+Law}}</ref>

| #In studying organic compounds, Kopp found a regular relationship between boiling points and the number of CH<sub>2</sub> groups present.<ref>See page 942 of {{cite book | title = Elements of Chemistry | author = Miller, William Allen | year = 1869| publisher = Longmans, Green, Reader, and Dyer | location = London | url = http://books.google.com/?id=b7ktAAAAYAAJ&pg=PA942&dq=Kopp%27s+law }}</ref>

| == Kopp–Neumann law ==
| |
| '''Kopp–Neumann law''' states that the [[specific heat]] ''C'' per unit [[mass]] (in J•kg<sup>−1</sup>•K<sup>−1</sup>) for [[alloy]]s can be calculated from the following equation:
| |
| | |
| <math>C=\sum_{i=1}^N(C_i \cdot f_i)</math>
| |
| | |
| where: ''i'' - subsequent numbers from 1 to ''N'', ''N'' - total number of alloy constituents, ''C<sub>i</sup>'' and ''f<sub>i</sup>'' - [[specific heat]] and [[mass fraction]] of the ''i''-th constituent.

They contact me Emilia. South Dakota is where I've always been residing. In her professional lifestyle she is a payroll clerk but she's always needed her personal business. He is truly fond of doing ceramics but he is having difficulties to find time for it.
