Carbon Dioxide melts at -78 degrees Centigrade. Carbon Dioxide will boil at -57 degrees C. Carbon Dioxide does not stay in liquid form unless certain parameters exist, it is a very temporary stage.
You Ultimately would not expect them to have similar melting and boiling points.This is because Carbon Dioxide is a gas, it might have strong covalent bonds between their atoms but between their molecules they have weak intermolecular forces, therefore these forces are easily overcome during heating in lower temperaturesHowever when you look at Silicon Dioxide, it has a macromolecular structure. In other words the whole solid is actually just one molecule which its atoms are each covalently bonded to each other. Therefore since it has strong covalent bonds between them you would expect them to have extremely high melting and boiling points.Diamond is a macromolecular structure and it has a melting point of 3006 degrees centigrade. You could expect Silicon Dioxide's melting point (and boiling point) to be similarly high.
Melting point: the temperature at which a solid become a liquid. Boiling point: the temperature at which a liquid become a gas.
normal melting and boiling points are those when the pressure is 1 atmosphere, Solid CO2 gets converted to gaseous state (sublimation) on decrease of pressure to 1 atmosphere
Some common properties of organic compounds include having covalent bonds, containing carbon and hydrogen atoms, being flammable, having low melting and boiling points, and often having a complex molecular structure.
Melting and boiling points are important characteristics of materials: they are needed in industry and in laboratory.
This because air is a mixture.
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.
Air is a mixture; it doesn't have a melting or boiling point. It has a mixture of carbon dioxide, ozone, oxygen, nitrogen, helium, etc. look up those gases separately and you will get answers.

Melting and boiling points are different for each compound or element.
i don't know but don't you have a textbook or something
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.
