The terms melting point or freezing point are often interchanged depending on whether a substance is being heated or cooled. Melting point:153 degrees celsius. However, at atmospheric pressure (pressure at sea level), instead of melting, carbon sublimes, it turns directly from a solid to a gas without melting into a liquid first. The melting point can be looked up in a reference book (this value would then be called the "literature melting point"), and compared to the experimental melting point. Barium Chloride has the highest melting point of 962 degree Celsius. Unaffected by water.

Adding a heat will convert the solid into a liquid with no temperature change. You can print the list of elements by hitting the print button below. List of Elements by Melting Point. Join. 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.. As heat is applied to a solid, its temperature will increase until the melting point is reached. This article has been tagged since{{{1}}}. However, if you include magnesium, you will see that its melting point is lower than the melting point of calcium, the next element down. Stable in air. Answer to: Decide which element probably has a melting point most and least similar to the melting point of lead. Explain briefly. Trending Questions. For liquids it is known as the freezing point and for solids it is called the melting point. Melting Point – Saturation. Trending Questions. The element gallium has a melting point of $29.8^{\circ} \mathrm{C} .$ If you held a sample of gallium in your hand, should it melt? To list the elements order by melting point and other properties click on the table headers. [Last Updated: 2/22/2007] Citing this page. Tungsten melts at extremely high temperatures that are 3,380 degrees Celsius whereas cesium has a very low melting point of 28.5°C. Still have questions? The strength of the van der Waals' forces decreases as the size of the molecule decreases, so the melting points and boiling points decrease in the order: S 8 > P 4 > Cl 2 > Ar. Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. Explanation: Cu has lowest melting point because it has lowest enthalpy of atomisation (i.e., heat required to break the metal lattice to get free atoms) among the elements. The melting point of a solid and the freezing point of the liquid are normally the same. Boiling Point: -154°C (or -245°F), 120 K. Density: 0.003733 g/cc. Give reasons for your choice.
