Is boiling endothermic or exothermic? Is evaporation endothermic or exothermic? Estimate the standard enthalpy change for the reaction 2H_2O_2(l) \to 2H_2O(l) + O_2(g). \Delta H_{vap}(H_2O_2) = 51.6 KJ/mol; \Delta H_{vap}(H...
Boiling point is a physical property. Vaporization is a physical change of state that does not involve a chemical reaction. Heating a liquid until it vaporizes allows the determination of the boiling point of the material. When the liquid is heated steadily, the temperature of the liquid rises ...
You've always got to have three sides of a triangle; if you take one of them away, you've lost your triangle. It's gone. The shape is absolutely minimum. You've got to have the three sides or two internal angles, and this is boiling things down to the absolute bare minimum. ...
