Melting point: the temperature at which a solid become a liquid. Boiling point: the temperature at which a liquid become a gas.


All substances have melting points and boiling points. A melting point is merely the temperarture at which it changes from a solid to liquid and vice versa. The boiling point of a substance would be the temperature at which it changes from liquid to gas and vice versa.


Melting point: the temperature of change from solid to liquid phase. Boiling point: the temperature of change from liquid to gas phase.


The melting point of a substance is the (thermal) point at which a solid substance gains enough thermal energy to become a liquid.The boiling point of a substance is the (thermal) point at which a liquid substance gains enough thermal energy to become a gas.Boiling point of water: 100 degrees C/ 212 degrees FMelting point of water: 0 degrees C/ 32 degrees FMelting points and boiling points are the temperature at which substances change state.Melting point - solid to liquidBoiling point - liquid to gasThese temperatures will vary depending on the properties of the substance.


If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.


Not all compounds have high melting points and high boiling points.


The boiling and melting points of pure substances vary based on the substance. Gasses for example have lower boiling and melting points than metals.


Melting and boiling points are different for each compound or element.


No. The melting and boiling points of liquids vary considerably.


They have high melting and boiling points and can conduct electricity when they are molten or a liquid.


Melting and boiling points of halogens increase down in the group.


A certain substance has certain melting and boiling points which is what helps identify a substance.


Ionic compounds generally have high melting points and boiling points with some notable exceptions e.g. NH4Cl which sublimes. Metals also generally have high melting points and boiling points, again there are some notable exceptions mercury a liquid at room temperture, gallium which melts in your hand.


Impurities can increase or decrease the melting and boiling points of substances depending on what the impurity is.


They have high melting points and very high boiling points


Compounds with strong intermolecular forces have higher melting and boiling points.




melting: 115.21 ºC boiling: 444.6 ºC


chloride isn't a thing on its own and the melting and boiling points of chlorine and magnesium will have no effect on the boiling and melting point og magnesium chloride.


There are 3 basic states of matter. These are solid, liquid and gas. The melting point is the temperature at which matter changes completely from solid to liquid, thereby melting. The boiling point is the point at which matter changes completely from liquid to gas, thereby evaporating. It isn't called evaporating point because many liquids partially evaporate long before reaching their boiling point. For water, the melting point is 0 degrees centigrade, and the boiling point is 100 degrees centigrade.


At 1atm, the melting point of H2O(water) is 0 degrees celcius and the boiling point is 100 degrees celcius. Carbon dioxide's boiling point is at -25 degrees and so its meting point. Since it crystallises and sublimates, it has no liquid form. The boiling- and melting points of elements/compounds depend on the amount of pressure exerted on the element/compound. Generally, the higher the pressure, the higher the boiling and melting points. All except for water, gallium and bismuth. These substances' melting point decreases as pressure increases.


Many substances have different melting and boiling points, thus one can use their melting and boiling points to identify them.



The melting point of solids and boiling points of liquids are intrinsic properties and can be used to identify them. And to separate mixtures as well, as in fractional distillation.
