Why do fullerenes have much lower melting and boiling points than other carbon forms?
Diamond has got a giant covalent structure which carbon atoms hold each other by strong covalent bond . However, in buckminsterfullerene, atoms packed closely together but bound by weak Van der Waal's force. Thus, buckminsterfullerene requires less heat to overcome the the attractive force than that of diamond.

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.
Why can we not talk about the melting and boiling point of air?
This because air is a mixture.
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 is the melting and boiling point of bucky balls?
The melting point of buckyballs (C60 molecules) is approximately 590 degrees Celsius, while the boiling point is around 881 degrees Celsius. Buckyballs have high melting and boiling points due to the strong covalent bonds within the carbon structure.
What are the melting and boiling points of cesium?
Melting point 28.5°C Boiling point 690°C
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.
How do you identify solids at melting or boiling points?
Melting and boiling points are different for each compound or element.
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.
