First law of thermodynamics: one of the most fundamental laws of nature is the conservation of energy principle. It simply states that during an interaction, energy can change from one form to another but the total amount of energy remains constant. Second law of thermodynamics: energy has quality as well as quantity, and actual processes occur ...

The Second Law of Thermodynamics For the free expansion, we have ΔS > 0. It is an irreversible process in a closed system. For the reversible isothermal process, for the gas ΔS > 0 for expansion and ΔS < 0 for compression. However, the gas itself is not a closed system. It is only a closed system if we include both the gas and the reservoir.

Thermodynamics is not concerned about how and at what rate these energy transformations are carried out, but is based on initial and final states of a system undergoing the change. Laws of thermodynamics apply only when a system is in equilibrium or moves from one equilibrium state to another equilibrium state. Macroscopic properties like

Ideal Gas Law This law combines the relationships between p, V, T and mass, and gives a number to the constant! The ideal gas law is: pV = nRT , where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K .

The composition law states that we should be able to quantify the uncertainty at each step and add them together. The uncertainty in 1st step is simply S(A) = S(p 1; ;p n). The uncertainty in 2nd step depends on the outcome of the 1st step. When basket k is selected, let the uncertainty of 2nd step be S(BjA k).
