: Boyle-Mariotte, Gay-Lussac, and the general gas equation. Ideal Gas Mixtures : Partial pressures and Dalton's Law.

Energija se ne može stvoriti ni uništiti, već samo transformisati. Za zatvoreni sistem, promena unutrašnje energije ( ) jednaka je razlici dovedene toplote ( ) i izvršenog rada ( ΔU=Q−Wcap delta cap U equals cap Q minus cap W Drugi zakon termodinamike

To find legitimate and high-quality educational materials, try searching university repositories. Many technical faculties publish open-access lecture notes.

) is vital, as it represents the "organized" or "high-grade" form of energy that can be directly harnessed for mechanical utility. 1. Fundamental Principles and Definitions : Boyle-Mariotte, Gay-Lussac, and the general gas equation

Rad je procesna veličina, što znači da njegova vrednost zavisi od puta kojim sistem prelazi iz početnog u krajnje stanje. Grafički se rad predstavlja kao površina ispod krive procesa u dijagramu. Matematička definicija elementarnog rada ekspanzije glasi: dW=p⋅dVd cap W equals p center dot d cap V

: Osnova rada savremenih parnih elektrana. Voda se pretvara u paru visokog pritiska, vrši koristan rad u turbini, kondenzuje se i pumpom vraća nazivajući proces ispočetka.

Da li vam je potreban za neku određenu vrstu rada (npr. tehnički rad u turbinama)?

Uvodi pojam entropije. Toplota ne može spontano prelaziti s hladnijeg na toplije tijelo. Svi prirodni procesi teže povećanju nereda (entropije). Za zatvoreni sistem, promena unutrašnje energije ( )

Calculating the efficiency of cycles like Carnot, Otto, or Diesel. Steam Cycles: Using

Divided into natural (buoyancy-driven) and forced (pump or fan-driven) convection. Governed by Newton's Law of Cooling: is the convection coefficient.
