Pv=nrt Memes

The top image shows a bottle of "Hard to swallow pills," while the bottom reveals the pills contain chemistry truths that shatter common oversimplifications. Sodium chloride (NaCl) isn't perfectly ionic - it's actually about 80% ionic with some covalent character. And PV=NRT (the ideal gas law) is just an approximation that falls apart under high pressure or low temperature conditions. Chemistry professors love presenting these simplified models before destroying your confidence with "but actually..." revelations later in your education. The real pill to swallow is that nearly everything in introductory chemistry is a convenient lie!

The meme perfectly captures that chemical engineering student who learned the ideal gas law (PV=nRT) and now thinks it's the universal solution to every thermodynamic problem. Spoiler alert: using ideal gas equations near critical pressure is like trying to predict weather with a Magic 8-Ball. The ideal gas law assumes gases behave... well, ideally—which they absolutely don't at extreme conditions where molecules start getting clingy with each other. The dog's disappointed expression in the final panel is basically every professor watching students apply oversimplified models to complex systems. It's the thermodynamic equivalent of bringing a plastic spoon to dig the Suez Canal.

The eternal chemistry student paradox: memorizing PV=nRT so thoroughly you could recite it in your sleep, yet still writing it on your cheat sheet "just in case." It's like having the nuclear launch codes tattooed on your arm but still keeping them in your wallet. Chemistry professors everywhere are silently judging while secretly doing the exact same thing with reaction mechanisms they've taught for 20 years. The real gas law should be: Confidence = (Knowledge × Preparation) ÷ Exam Anxiety.

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!"
