Explanation The following expression represents a fundamental thermodynamic function. u = u ( s , v ) Here, internal energy at specific entropy s and specific volume v is u ( s , v ) . Write the expression to calculate the temperature. T = ( ∂ u ∂ s ) v (I) Herer, the change in internal energy is ∂ u ∂ s . Write the expression to calculate the pressure. p = − ( ∂ u ∂ v ) s (II) Here, the change in internal energy wth respect to spevific volume is ∂ u ∂ v . Write the expression for the specific enthalpy. h = u + p v (III) Here, the specific volume is is v and internal energy is u . Write the expression to calculate the helmontz function. ψ = u − T s (IV) Here, the specific entropy is s . Write the expression to calculate the gibbs function. g = h − T s (V) Conclusion: Substitute u ( s , v ) for u in Equation (I). p = − ( ∂ ( u ( s , v ) ) ∂ v ) s Substitute u ( s , v ) for u in Equation (II). p = − ( ∂ ( u ( s , v ) ) ∂ v ) s Substitute − ( ∂ u ∂ v ) s for p in Equation (III). h = u + ( − ( ∂ u ∂ v ) s ) v (VI) Substitute u ( s , v ) for u in Equation (VI)

Properties of Pure Substances

A substance with fixed chemical composition throughout is called a pure substance like water, air, and nitrogen. A pure substance does not have to be a single element or compound. A mixture of two or more phases of a pure substance is also a pure substan…
