Instead of generally increasing or decreasing trend, melting and boiling points reach two different peaks as d and p orbitals fill. -Darryn

How do the melting and boiling points of water differ from those of a sugar water solution?
The phenomenon of boiling point elevation is analogous to freezing point depression
How do ionic compounds and molecular compounds differ in their relative melting and bioling points?
Ionic compounds have higher melting and boiling points than molecular compounds do. The electronegativity difference in ionic compounds makes their bond much stronger.
Why do the melting and boiling points of a particular subsatnce vary?
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.
What characteristic property of two liquids must differ if a mixture of them is to be separated by fractional distillation?
The characteristic property that allows distillation to separate a mixture of liquids is a liquids boiling point. The conducting vapors are put in a cooling device where they are allowed to condense. The condensation is collecting into a different flask.
How does the boiling process at supercritical pressures differ from the boiling process at subcritical pressures?
there is no distinct phase change as it just simply evaporates
How do differ boiling and melting?
Boiling - is turning a liquid into a gas. Melting is turning a solid into a liquid.
How do the melting and boiling points of water differ from those of a sugar water solution?
The phenomenon of boiling point elevation is analogous to freezing point depression
What is Iron's melting and boiling points?
Melting point of iron=1535oC Boiling point of iron=2750oC
Two factors that are responsible for a phase change?
Change in pressure and change in temperature.
How do ionic compounds and molecular compounds differ in their relative melting and bioling points?
Ionic compounds have higher melting and boiling points than molecular compounds do. The electronegativity difference in ionic compounds makes their bond much stronger.
How do the boiling and freezing points between the Fahrenheit and celsius?
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.
What is melting point of a solid?
the melting points differ to differant solids
Explain why the boiling point and the melting point can be used to help identify substances?
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.
If you performed a melting point experiment in the laboratory and on the top of the mountain would your results differ explain?
Yes because the atmospheric pressure at mountain is lower, therefore m.p becomes lower

Why do rows in the periodic table differ in length?
tthere ordered by numbers
