On Penguins and Thermodynamics

As predicted, here's another in the chemistry poetry book illustration series. In the thermodynamics chapter, one of the poems likens NO2 molecules to penguins. They huddle together for warmth, but then are pleasantly surprised to find that they react with each other to make N2O4. The exothermic reaction gives them their desired warmth after all. It sounds much better in Mala's words, you'll see.
