The struggle is REAL with real gases! Physical chemistry students everywhere are united in their frustration when ideal gas equations get crashed by reality. The ideal gas equation (PV=nRT) is that perfect friend who never complicates things - pressure times volume equals the number of moles times the gas constant times temperature. Clean. Simple. Beautiful.
But then real gases show up with their molecular attractions and finite volumes, demanding complex equations with correction factors. It's like expecting a straightforward calculation and suddenly needing calculus, three extra variables, and possibly a small sacrifice to the thermodynamics gods. No wonder these students are throwing up the universal sign for "give me back my idealized mathematical models!"
