Highest melting temperature
WebExpert Answer. Which of the following forms of PTFE would you expect to have the highest melting temperature? All of these options offer the same melting temperature Mn 150,000 g/mol, 5% crystalline, linear Mn-150,000 g/mol, 20% crystalline, linear Mn-150.000 g/mol, 70% crystalline, linear Mn-150.000 g/mol, 70% crystalline, branched . The metal with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as electrical filaments in incandescent lamps. Ver mais The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on Ver mais Many laboratory techniques exist for the determination of melting points. A Kofler bench is a metal strip with a temperature gradient (range from room temperature to 300 °C). Any substance can be placed on a section of the strip, revealing its thermal behaviour at the … Ver mais In organic chemistry, Carnelley's rule, established in 1882 by Thomas Carnelley, states that high molecular symmetry is associated with high … Ver mais For most substances, melting and freezing points are approximately equal. For example, the melting point and freezing point of mercury is 234.32 kelvins (−38.83 °C; −37.89 °F). However, certain substances possess differing solid-liquid transition temperatures. For … Ver mais For a solid to melt, heat is required to raise its temperature to the melting point. However, further heat needs to be supplied for the … Ver mais The freezing point of a solvent is depressed when another compound is added, meaning that a solution has a lower freezing point than a … Ver mais An attempt to predict the bulk melting point of crystalline materials was first made in 1910 by Frederick Lindemann. The idea behind the theory was the observation that the average amplitude of thermal vibrations increases with increasing temperature. … Ver mais
