Unutrašnja energija

U=Ek + Ep - dzul je m jedinica


U=Ek za idealni gas


Ek=3/2 m/M RT

Unutrasnja energija za dvoatomski gas

U=5/2 m/M RT

Količina toplote

Q = deltaU + A dzul

Rad

A = p * delta V dzul

Količina toplote kod procesa

kod izotermskih Q=A


izohorskih Q=deltaU


izobarskih Q=deltaU + p*delta V


Adijabatskih A=-deltaU

Cv i Cp

C = Q/deltaT


p=const


V=const

Specifična toplotna kapacitivnost

c = Q/m deltaT

Entropija

delta S = delta Q/T


Koristan rad

Q1=A+Q2 + deltaQ + deltaU

Rad za idealne i realne motore

A= Q1-Q2 za idealne


A<Q1-Q2 za realne

Koeficijent korisnog dejstva

Eta = A/Q1 = 1 - T2/T1


Eta = T1-T2 sve kroz T1
