영어에서 ENTHALPY 의 뜻은 무엇인가요?
엔탈피
엔탈피는 시스템의 내부 에너지와 압력의 곱과 시스템의 체적으로 구성된 문자 "H"로 지정된 정의 된 열역학 잠재력이다. 엔탈피 H는 내부 에너지 U와 제품 압력과 시스템의 부피는 열역학적 시스템의 모든 기능이며, 엔탈피는 상태 함수이다. 국제 단위계에서 엔탈피를 측정하는 단위는 줄이지만 다른 영국의 열량 단위와 칼로리와 같은 기존의 단위는 여전히 사용되고 있습니다. 엔탈피는 많은 화학적, 생물학적 및 물리적 측정에서 시스템 에너지 변화의 바람직한 표현입니다. 이는 에너지 전달의 특정 설명을 단순화하기 때문입니다. 엔탈피 변화는 팽창이나 가열을 통해 일정한 압력으로 환경으로 전달되는 에너지를 설명합니다. 시스템의 전체 엔탈피 H는 직접 측정 할 수 없습니다. 고전 역학에서는 에너지의 변화 나 차이 만이 물리적 의미를 지닙니다.
영어 사전에서 enthalpy 의 정의

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 ~
