The combined effect of these drying stresses in a wood element often, and sometimes inevitably, results in the formation of a check or a split. Since the weakest strength property in wood is tension perpendicular to the grain (similar to the manner in which wood is split using an ax), drying stresses can result in a check or split that form in a radial direction across the annual rings.

NO2 N2O4 Equilibrium UW Dept. of Chemistry

Heat shifts the equilibrium in favor of NO2 and the tube becomes darker. Since the formation of N2O4 is an exothermic reaction, lowering the temperature shifts the equilibrium in favor of colorless N2O4. In a dry ice acetone bath, the N2O4 will crystallizes as a white solid.
