समीकरण जो एक संपीड्य द्रव के p, v, T और s गुणों के आंशिक अवकलजों को संबंधित करते हैं, उन्हें मैक्सवेल संबंध कहा जाता है।
चार गिब्सियन संबंध एक इकाई द्रव्यमान के लिए हैं
1) du = Tds - Pdv
2) dh = Tds + vdP
3) df = - Pdv - sdT
4) dg = -sdT + vdP
चूँकि u,h,f और g गुण हैं इस प्रकार बिंदु फलन हैं और उपरोक्त संबंधों को इस प्रकार व्यक्त किया जा सकता है
dz = Mdx + Ndy
जहाँ,
\({\left( {\frac{{\partial T}}{{\partial v}}} \right)_s} = \; + {\left( {\frac{{\partial p}}{{\partial s}}} \right)_v}\)
चक्रीय संबंध को लागू करने पर
Mdx + Ndy → \({\left( {\frac{{\delta M}}{{\delta y}}} \right)_x} = {\left( {\frac{{\delta N}}{{\delta x}}} \right)_y}\)
अब,
गिब्सियन समीकरणों में से प्रत्येक के T,p,v,s को चक्रीय क्रम में M,N,y और x से बदलने पर, हमें निम्नलिखित चार संबंध प्राप्त होंगे।
\(1){\left( {\frac{{\partial T}}{{\partial p}}} \right)_s} = {\left( {\frac{{\partial v}}{{\partial s}}} \right)_p}\;\)
\(2){\left( {\frac{{\partial p}}{{\partial T}}} \right)_v} = {\left( {\frac{{\partial s}}{{\partial v}}} \right)_T}\;\)
\(3){\left( {\frac{{\partial T}}{{\partial v}}} \right)_s} = - {\left( {\frac{{\partial p}}{{\partial s}}} \right)_v}\)
\(4){\left( {\frac{{\partial v}}{{\partial T}}} \right)_p} = - {\left( {\frac{{\partial s}}{{\partial p}}} \right)_T}\)
