WitrynaA certain amount of NOBr(g) is sealed in a flask, and the temperature is raised to 350 K. The following equilibrium is established: $$ NOBr(g) ↔ NO(g) + ½ Br2(g) $$ The total pressure in the flask when equilibrium is reached at this temperature is 0.675 atm, and the vapor density is 2.219 g L^-1. Witryna1 lip 2012 · In addition, it is common to include transition metal oxides to provide colour to the glaze. A potter needs to consider three important properties of a glaze. These are the texture (rough or smooth), opacity (clear or opaque) and colour. The first two are best considered together in terms of the melting properties of solid mixtures.
Witryna14 maj 2024 · Detailed Solution The correct answer is Option 1. Melting of iron metal, Bending of iron rod, tempering of iron, and drawing a wire of iron metal – are examples of Physical Changes of Iron. Hence option 1 is incorrect. Rusting of iron is an example of chemical change. Melting, or fusion, is a physical process that results in the phase transition of a substance from a solid to a liquid. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point. At the melting point, the ordering of ions or molecules in the solid breaks down to a less ordered state, and the solid melts to become a liquid.
