Instead of generally increasing or decreasing trend, melting and boiling points reach two different peaks as d and p orbitals fill. -Darryn
Metals on the periodic table are elements that are typically shiny, malleable, and good conductors of heat and electricity. Their properties differ from nonmetals and metalloids in that metals tend to be more ductile, have higher melting and boiling points, and are more reactive. Nonmetals, on the other hand, are typically brittle, poor conductors of heat and electricity, and have lower melting and boiling points. Metalloids have properties that are intermediate between metals and nonmetals.
The melting and boiling points of water are higher than those of a sugar water solution because the presence of sugar disrupts the hydrogen bonding between water molecules. This disruption lowers the melting and boiling points of the solution compared to pure water.
It is because the intermolecular forces(the attractive forces between the molecules of a substance) differ from one substance to another. The chemical with the stronger intermolecular forces will have higher melting and boiling points, and vice versa. This is because more energy is required to separate the molecules to melt or boil the substance, if the forces are strong. The factors that determine the size of these forces are :the type of bonding in the molcules, andthe mass of the molecules.
Ionic compounds tend to have higher melting and boiling points compared to molecular compounds. This is because ionic bonds are generally stronger than the intermolecular forces present in molecular compounds, such as van der Waals forces. The strong electrostatic forces between ions in an ionic compound require more energy to overcome, leading to higher melting and boiling points.
The boiling points of the two liquids must differ in order to be separated by fractional distillation. This technique relies on heating the mixture to separate the components based on their boiling points. The greater the difference in boiling points, the more effective the separation will be.
Boiling - is turning a liquid into a gas. Melting is turning a solid into a liquid.

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.

Melting point of iron=1535oC Boiling point of iron=2750oC
Yes, the results could differ because the atmospheric pressure varies with altitude, which can affect the boiling point of liquids, including the melting point of solids. The lower atmospheric pressure at the top of a mountain can cause the melting point of a substance to be slightly lower than at sea level.

Boiling points and melting points differ for different elements and compounds. However, if water is considered, the freezing point is 0 degree Celsius which is 32 degree Fahrenheit. Boiling point is 100 degree Celsius which is 212 degree Fahrenheit.

Ionic compounds tend to have higher melting and boiling points compared to molecular compounds. This is because ionic bonds are generally stronger than the intermolecular forces present in molecular compounds, such as van der Waals forces. The strong electrostatic forces between ions in an ionic compound require more energy to overcome, leading to higher melting and boiling points.
Temperature and pressure are two factors that can cause a phase change in a substance. A substance will change from one phase to another when its temperature or pressure surpass a certain threshold, known as the melting point, boiling point, or sublimation point.
100 degrees mate. 100 degrees Celsius is the boiling point for pure water at 1atm or sea level. The boiling point is useful in identifying chemical compounds. Chemical compounds have different boiling points that are specific to it' s chemical composition. If you know what the boiling point or melting point is you can also tell if your compound is pure, as any impurities will change these.
