APAKAH MAKSUD ENTHALPY dalam CORSICA?
Enthalpy
Enthalpy adalah potensi termodinamik yang ditakrifkan oleh surat "H", yang terdiri daripada tenaga dalaman sistem ditambah dengan produk tekanan dan volum sistem: Oleh kerana entalpi, H, terdiri daripada tenaga dalaman, U, ditambah dengan produk tekanan dan volum sistem, yang semua fungsi keadaan sistem termodinamik, entalpi adalah fungsi keadaan. Unit pengukuran untuk entalpi dalam Sistem Unit Antarabangsa adalah joule, tetapi unit bersejarah, konvensional lain masih digunakan, seperti unit termal British dan kalori. Entalpi adalah ungkapan pilihan perubahan tenaga sistem dalam banyak ukuran kimia, biologi, dan fizikal, kerana ia memudahkan deskripsi tertentu pemindahan tenaga. Enthalpy menukar akaun untuk tenaga yang dipindahkan ke alam sekitar pada tekanan tetap melalui pengembangan atau pemanasan. Keseluruhan entalpi, H, sistem tidak boleh diukur secara langsung. Keadaan yang sama wujud dalam mekanik klasik: hanya perubahan atau perbezaan dalam tenaga membawa makna fizikal.
Definisi enthalpy dalam kamus Corsica
Takrif entalpi dalam kamus adalah sifat termodinamik sistem yang sama dengan jumlah tenaga dalamannya dan produk tekanan dan volumnya H Juga dipanggil: kandungan haba, jumlah haba.

Fortunately, air conditioning involves only a calculation of changes in enthalpy. It
follows that such changes may be readily determined if a datum level of enthalpy
is adopted for its expression. Thus, we are really always dealing in relative ...

An arrow pointing upwards indicates a process in which the enthalpy change is
positive (enthalpy is taken in). AHf = AHf + AHf + AHf + AHf + AHf =-604kjmol"1 2.
The method is simply AH^erum = AHf (products) - AHf (reactants) [see § 10.4.2].

The very negative value of the estimated enthalpy of hydration of the proton is

overestimates the ionic radius by —67 pm it follows that a "bare" proton (radius ~
