Al2O3 has a melting point of 2072 oC, and NaBr has a melting point of 747 oC.
Amorphous solids have no definite melting point because their particles are arranged randomly. Amorphous solids do not have crystal form or definite melting point.
because amorphous solids are that solids that don't have geometrical shape and don't have particular melting point but crystalline solids have characterstic geometrical shape and have sharp melting point.
Name this crystalline solid; each compound and material have a different melting point.
The boiling point is always higher than the melting point.
The melting point of bromine is -7,2 0C. The melting point of chlorine is -101,5 0C.
Ionic compounds have a higher melting point.
Network solids have a three-dimensional structure with strong covalent bonds throughout, leading to a higher melting point compared to molecular solids which have weaker intermolecular forces. In network solids, a larger amount of energy is required to break the extensive network of covalent bonds, resulting in a higher melting point.
Ionic compounds have a higher melting point.
Amorphous solids have no definite melting point because their particles are arranged randomly. Amorphous solids do not have crystal form or definite melting point.
the melting points differ to differant solids
Covalent compounds have a lower melting point.
Covalent compounds have a lower melting point.
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.
melting point..
The melting point of a solid depends on the strength of the bonds holding its particles together. Solids with stronger intermolecular or intramolecular forces require more energy input to break these bonds, resulting in a higher melting point. Factors such as molecular size, shape, and polarity can influence the strength of these bonds, leading to variations in melting temperatures between different solids.
because amorphous solids are that solids that don't have geometrical shape and don't have particular melting point but crystalline solids have characterstic geometrical shape and have sharp melting point.
The hypothesis for the melting and freezing point of naphthalene could be that the melting point of naphthalene will be higher than its freezing point due to the typical behavior of most substances where solids melt at higher temperatures than they freeze. The hypothesis may also include factors like the purity of the naphthalene sample affecting its melting and freezing points.
