KINDS OF THERMODYNAMIC PROCESSESADIABATIC – NO HEAT TRANSFER; Q = 0; DU = -WISOCHORIC – CONSTANT VOLUME; DU = Q ISOBARIC – CONSTANT PRESSURE; W = p (V2 – V1)ISOTHERMAL – CONSTANT TEMPERATURE; only for ideal gas DU = 0, Q = W

The First Law of Thermodynamics

Q = DU + W or DU = Q - W

Fig. 17-13 Processes for an ideal gas:adiabatic Q=0isochoric W=0isothermal DU=0

Fig. 17-14 The internal energy of an ideal gas depends only on its temperature, not on its pressure of volume.

Q = DU + W and DU= f(T)Isochoric W=0 so Q=DUIsobaric Q = DU + p(V2-V1)
