It states that the amount of heat is equal to the sum of change in internal energy and amount of workdone dQ=dU+dW. [dW=PdV] --------------------------------------------------------------------------- Relation between Cp &Cv According to first law of thermodynamics. dQ=dU+dW-----(1) diffenciate w.r.t.time(t) dQ/dt=dU/dt+PdV/dt Cv=dQ/dt v=constant dV=0 Cv=dU/dt----(2) Cp=dQ/dt Cp=dU/dt+PdV/dt-----(3) Equation(3)-(2) Cp-Cv=PdV/dt------(4) PV=Rt [n=1mole] Differentiate w.r.t.time(t) PdV/dt=Rdt/dt=R [Cp-Cv=R]

Sajid Khan 8 years, 1 month ago

The second law of thermodynamics says that when energy changes from one form to another form, or matter moves freely, entropy (disorder) in a closed system increases. Differences in temperature, pressure, and density tend to even out horizontally after a while. Due to the force of gravity, density and pressure do not even out vertically. Density and pressure on the bottom will be more than at the top.

Sajid Khan 8 years, 1 month ago

Hess's Law of Constant Heat Summation is useful in the determination of enthalpies of the following:[1] Heats of very slow reactions Heats of formation of unstable intermediates like CO(g) and NO(g). Heat changes in phase transitions and allotropic transitions. Lattice energies of ionic substances by constructing Born-Haber cycles if the electron affinity to form the anion is known, or Electron affinities using a Born-Haber cycle with a theoretical lattice energy
