Melting and boiling points are different for each compound or element.
Well,its because the particles that constitute solids are closer together hence the forces of attraction are greater rising the boiling point and melting points are raised as the heat try to break the bonds
in crystalline solids, the atoms are arranged in an ordered fashion and hence they have sharp melting points. amorphous solids, due to random arrangement of the atoms do not have sharp melting points.
No, the trends for melting points and boiling points in nonmetals are generally different from those in metals. Nonmetals typically have lower melting and boiling points compared to metals, which tend to have high melting and boiling points due to strong metallic bonds. In nonmetals, the melting and boiling points can vary significantly based on molecular structure and intermolecular forces, with noble gases having very low points and some covalent network solids like diamond having high points. Therefore, while both groups exhibit trends, the underlying reasons and values differ significantly.
Generally they are two types of solids 1. Crystalline solids 2. Amorphous solids. Amorphous solids are those solids which having different properties in different directions. They didnt have sharp melting and boiling points.
Molecular solids
the melting points differ to differant solids
Simple molecular substances typically have low melting and boiling points. This is because the weak intermolecular forces, such as London dispersion forces, in simple molecular substances are easily overcome compared to the stronger bonds in ionic or metallic substances.
Solids made of atoms
No, amorphous solids do not have sharp melting points like crystalline solids. Instead, amorphous solids soften over a range of temperatures as they transition into a more fluid state, making their melting behavior less well-defined.
Ionic compounds have a higher melting point.
The phase of matter for each element can be determined based on its melting point and boiling point. Elements with low melting and boiling points, such as hydrogen and helium, are typically gases at room temperature. Elements with higher melting and boiling points, such as iron and aluminum, are typically solids at room temperature. Elements that are in between, like mercury, can be liquids at room temperature.
The boiling point of a liquid is influenced by pressure: lower pressure leads to lower boiling point. Therefore, reporting the pressure at which the boiling point was measured gives context to the boiling point value and ensures consistency in comparison among different samples.
