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, and
- the mass of the molecules.

Do all liquids have the same boiling and melting point?
No, different liquids have different boiling and melting points depending on their chemical composition. The boiling point is the temperature at which a liquid turns into a gas, while the melting point is the temperature at which a solid turns into a liquid. Each liquid has its own unique set of physical properties that determine its specific boiling and melting points.
How melting and boiling points are affected by intermolecular forces?
Melting and boiling points are higher when intermolecular forces (such as hydrogen bonding, dipole-dipole interactions, or London dispersion forces) are stronger. These forces hold molecules together, so more energy is required to overcome them and change the state of the substance. Conversely, weaker intermolecular forces result in lower melting and boiling points.
What are the melting and boiling points of cesium?
Melting point 28.5°C Boiling point 690°C
What are the melting and boiling points of iodine?
Melting point 113.5°C Boiling point 184.35°C
How can the melting and boiling point help you identify it?
Melting and boiling points are physical properties unique to each substance, so knowing these values can help identify a substance. By comparing the observed melting and boiling points of an unknown substance to known values in a database, you can narrow down the possible identities of the substance. Substances with similar melting and boiling points are more likely to be the same compound.
How do you identify solids at melting or boiling points?
Melting and boiling points are different for each compound or element.
Do elements compounds and mixtures have fix melting and boiling point?
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
Why do the melting and boiling points of a particular substance virile?
The melting and boiling points of a substance are determined by the strength of intermolecular forces between its molecules. Substances with stronger intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, will have higher melting and boiling points. Conversely, substances with weaker forces, like London dispersion forces, will have lower melting and boiling points. Therefore, the specific type and strength of intermolecular forces present in a substance dictate its melting and boiling points.
Do all liquids have the same boiling and melting point?
No, different liquids have different boiling and melting points depending on their chemical composition. The boiling point is the temperature at which a liquid turns into a gas, while the melting point is the temperature at which a solid turns into a liquid. Each liquid has its own unique set of physical properties that determine its specific boiling and melting points.
What is melting points and the boiling points?
Melting point: the temperature at which a solid become a liquid. Boiling point: the temperature at which a liquid become a gas.
