dc.description.abstractThe paper is based on the fact that the internal energy, enthalpy and enthropy as most important thermodynamic state functions, can not be determined in absolut terms without reference state slections. It is demonstrated that to determination must be approached very cautiously. The reason for this is possibility of errors that are not permissible. The beginning conditions of measurement can be adopted. It is also necessary to pay attention to the beginning the measurement of the adopted reference value. For a case to be simultaneous determination of multiple state functions, it should take to account the beginning of the measurement of each of these functions, since this start may different. In this way the calculated state function vares, depending on refenece state is adopted. At the end, in one convenient example, in the case internal energy and enthalpy, as a characteristic state function, is pointed to possiility errors, which could occur if there is no detailed analysis of adopted reference of „zero“ state.en
dc.description.abstractU radu je, polazeći od činjenice da se unutrašnja energija, entalpija i entropija kao najvažnije termodinamičke veličine stanja, ne mogu odrediti u apsolutnom iznosu bez izbora referentnog stanja, pokazano da je pri ovom određivanju potrebno pristupiti veoma obazrivo. Razlog za ovo je mogućnost grešaka koje nisu dopustive. Pri ovome usvojeni početak merenja može u opštem slučaju biti različit. Neophodno je takođe obratiti pažnju na definisanost određene veličine stanja za usvojenu referentnu vrednost. Za slučaj da se vrši istovremeno određivanje više veličina stanja, treba voditi računa o početku merenja svake od ovih veličina, s obzirom da ovaj početak može biti različit. Na ovaj način izračunata veličina stanja zavisi od toga koje referentno stanje je usvojeno. Na kraju rada, koristeći praktičan računski primeru, za slučaj unutrašnje energije i entalpije, kao karakterističnih veličina stanja, ukazano je na mogućnost greške, koja se može javiti ukoliko se ne izvrši detaljna analiza izbora referentnog, odnosno „nultog“ stanja.sr
