This question is unanswerable because anything that sublimes won't ever melt.
Because sublime = the change from solid to gas, while at no point becoming a liquid.
and melting = the process of heating a solid substance to a liquid
I would beg to differ. Sublimation depends on other variables as well, i.e. pressure. (lower pressure)
Water is a substance that sublimates and melts. It's sublimation point is actually lower than it's melting point (if it were higher the substance would be in it's transition state... defeating the purpose)
I don't know nearly enough to tell you anything else, except that in a single substance, it is more likely that the sublimation point is lower.
the sublimation point in such things there are 5 in each sublimation point.
It is used to seperate substances of different melting point
The process in which solid directly changes into gas is called sublimation. Solid carbon dioxide is a substance that changes directly into gas without melting. Sublimation happens because these substances have higher vapor pressure than melting point.
Argon has the higher melting point.
Granite has a higher melting point than iron.
Generally the ionic molecules has a higher melting point.

Each substance has a specific melting point (excepting cases of sublimation or thermal degradation).
CaO has a higher melting point.
Argon has the higher melting point.
It heats up, until it reaches the melting point or sublimation point of the solid.
The boiling point is always higher than the melting point.
Granite has a higher melting point than iron.
yes, for the same molecule. However, some substances don't have a liquid phase and so the melting point is exactly the same as the boiling point at normal pressures (sublimation is the phase change from solid -> gas)
Generally the ionic molecules has a higher melting point.
Solids turn into liquids at their melting point.
The melting point.
