What two processes are involved with the formation of an ignerous rock?
melting and crystallization
How can melting point and boiling point determination be used in identifying and or characterizing unknown compounds?
compounds are identified because each compound have characteristically different melting and boiling points.
Which have higher boiling points organic or inorganic compounds?
Due to the different density of objects there will be a variety of melting points
Which process changes sedimentary rock into igneous?
Melting and crystallization.
Does the melting point depend on the substances being melted?
Yes, because the melting point depends on the strength of the intermolecular forces, which are different for different molecules and compounds. Stronger intermolecular forces mean a higher melting point.

How is partial melting related to fractional crystallization?
Partial melting occurs in rocks because the different minerals that compose rocks have different melting points. For example, felsic minerals (e.g. quartz and feldspar) melt at around 700 degrees Celsius while mafic minerals (e.g. pyroxene and olivine) melt at around 1200 degrees Celsius. Therefore, felsic minerals will melt first leaving the mafic minerals solid.Fractional crystallization occurs when minerals from a magma cool and crystallize out of the magma. The first crystals to melt in partial melting will be the first minerals to crystallize out when the magma begins to cool. Therefore, mafic minerals will crystallize first, followed by felsic minerals.Both partial melting and fractional crystallisation tend to produce a more felsic magma than their source rocks.The difference is simply that they are the reverse of one another, heat it up, cool it down. Things that melt first solidify last and separate from one another.
How is partial melting the opposite of fractional crystallization?
They're the same point, but reached from opposite directions. ie, partial melting is where a solid has partially melted into a liquid, while fractional crystallisation is where a liquid has only partially become a solid.
Why do covalent compounds and ionic compounds have different melting points?
Melting points are a reflection of the intermolecular forces and intramolecular forces of the compound. The stronger the intermolecular force, the more energy it takes to bring it to a different state.
Do different liquids share the same melting point?
No , most liquid compounds have different MP.
How can melting point and boiling point determination be used in identifying and or characterizing unknown compounds?
compounds are identified because each compound have characteristically different melting and boiling points.
How are the melting points and boiling point of molecular compounds different from ionic compounds?
they have diferent temp. also the ionic compounds dont melt they steam
Which process changes igneous rock into igneous rock?
Melting and crystallization.
Which have higher boiling points organic or inorganic compounds?
Due to the different density of objects there will be a variety of melting points
How does two different pure organic compounds can have the same melting point?
two different pure organic compounds may have same melting points because may be they share their nature of chemical bonds.
How does melting point compare among molecular compounds and ionic compounds?
Molecular compounds tend to have lower melting points.
How does the melting point of ionic compounds compared to that of covalent compounds?
Ionic compounds generally have higher melting and boiling points.
