No, boiling points are always higher than melting points. When you turn a solid to a liquid, this process is called melting, and requires a lower temperature than boiling the substance. Take ice water for example. Ice becomes pure water at 0oC. The temperature needed to boil pure water is 100oC, which is a bigger number than zero.

the relationship between the melting points and boiling points is simply that the higher the melting point, the higher the boiling point. the metal has to melt before it can boil, so if it didn't melt, it won't boil. there fore, the higher the melting point, the higher the boiling point ill be.

The greater the intermolecular attraction, the higher the melting point and boiling point. Melting and boiling are both processes which have to overcome intermolecular attraction.

The stronger the intermolecular forces, the higher the melting point and boiling point. The weaker the intermolecular forces, the lower the melting and boiling points are.

The boiling point is always higher than the melting point.

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.

The stronger the IMF, the higher the boiling point and the lower the melting point. The weaker the IMF, the lower the boiling point and the higher the melting point.

The boiling and melting point of Glucose To find the boiling point you boil it and to find the melting point you have to freeze it and melt it.

Boiling and melting points are very different.

Melting point 28.5°C; boiling point 690°C

Boiling Point 27.07 K Melting Point 24.56 K

Melting point of iron=1535oC Boiling point of iron=2750oC

Melting point 28.5°C Boiling point 690°C

Boiling point 58.78°C Melting point 7.2°C

Melting point 113.5°C Boiling point 184.35°C

The melting point is 3,375 F and the boiling point is 4,840 F.

The melting and boiling points are independent on the size.

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

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

Generally metals have higher melting and boiling points than nonmetals; but differences among metals are important.

mixture has varialble boiling and melting points, compound has a fixed boiling and melting and elements also have fixed boiling and melting point

Here are its melting and boiling points:Melting Point: -189.3 °C - 83.85 °KBoiling Point: -186.0 °C - 87.15 °K

impurities lower the magnitude of melting point of as substance. And it increases the magnitude of boiling point.

Melting points and boiling points are phyical constants which means specific compounds have specific melting/boiling points. Therefore you can identify a substance if you determine the mp/bp. Also you measure the purity of a mixture using melting point tests.
