HEAT OF FORMATION SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
Standart oluşum entalpisi
Bir bileşiğin oluşumunun standart entalpisi ya da standart ısı oluşumu, bileşimin 1 mol'ünün oluşumundan gelen entalpi değişikliğidir ve bütün maddeler 1 atmosferde standart halindedir. Onun sembolü ΔHfO veya ΔfHO'dur. Bu simgedeki üst simge teta, işlemin belirtilen sıcaklıktaki standart koşullar altında gerçekleştiğini gösterir. Standart haller aşağıdaki gibidir: ▪ Bir gaz için: standart devlet tam olarak 1 atm'lik bir basınçtır. ▪ İdeal bir solüsyonda bulunan bir çözünürlük için: 1 atm'lik bir basınçta tam olarak 1 M'lik bir konsantrasyon ▪ Saf bir madde veya Çözücü yoğunlaştırılmış haldedir: standart durum, 1 atm basınç altında saf sıvı veya katıdır. ▪ Bir element için: 1 atm basınç altında elementin en kararlı olduğu şekli. Bir istisna, 1 atm 'de en kararlı formun siyah fosfor olduğu fosfordur, ancak beyaz fosfor, sıfır oluşum entalpisi için standart referans hali olarak seçilmiştir.
İngilizce sözlükte heat of formation sözcüğünün tanımı
Sözlükteki oluşum ısısının tanımı, bir bileşiğin kurucu atomlarından oluştuğu zaman, evrimleşmiş veya emilen ısıdır.

The molal integral heat of dilution, i.e., the heat of diluting, with у moles of H2O, a
solution of one g.f.w. of the substance in x moles of H2O is the excess of the heat
of formation of 1 g.f.w. of the substance in the final solution over its heat of ...

The heat of formation of a compound is the net difference between the heat
content of the compound and that of its elemental constituents. Since the
elemental constituents are taken as zero by convention, it follows that the heat
content of a ...

For example, the heat of formation of cy- clohexane is -29.9 kcal / mol. What is the
meaning of this number? The fact that it is negative means that Eq. 2.9 is
exothermic. In other words, a mole of cyclohexane is more enthalpically stable
than the ...

Cracking the MCAT with CD-ROM
The heat of formation (AHf) of a substance is the enthalpy required for the
formation of one mole of that substance from its elements. The standard heat of
formation (AH,1) is the change in enthalpy for such a process under standard
conditions.
