Melting point - the temperature at which a solid turns into a liquid; See Standard state and enthalpy of formation, Gibbs free energy of formation, entropy and heat capacity for thermodynamic data for the same compounds. "Melting point is a really difficult prediction problem compared to what has been done before," co-author Axel van de Walle said in a press release. Join Yahoo Answers and get 100 points today. Chapter 1 Matter and Measurement Chemistry and Chemical Reactivity 6th Topics. K (Kelvin) Notes. The terms melting point or freezing point are often interchanged depending on whether a substance is being heated or cooled. There is a general decrease in melting point going down group 2. For liquids it is known as the freezing point and for solids it is called the melting point. Unaffected by water. Titanium carbide is widely used in the manufacture of cermet, heat resistant alloy, hard alloy, wear-resistant material, high-temperature radiation material, and other high-temperature vacuum devices. 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 pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa.. The correct option is (d) Cu.. The melting point of a solid and the freezing point of the liquid are normally the same. However, if you include magnesium, you will see that its melting point is lower than the melting point of calcium, the next element down. Softer than lead. Other temperature scales include the centigrade (Celsius) scale and the Fahrenheit scale. Give reasons for your choice. Melting points of the elements. In fact, cesium atoms are larger than those of any other element . Explain briefly.

There does not appear to be a trend in boiling points going down the group. Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. There is a list of high melting point elements as follows: To meet Chemistry Wiki's quality standards, this article or section may require cleanup. Tungsten melts at extremely high temperatures that are 3,380 degrees Celsius whereas cesium has a very low melting point of 28.5°C. Therefore the correct option is D. The melting point of Si is the highest in Period 3 elements but do take note this doesn't mean all giant molecules have higher melting points than all metals. Sponsored Links .
