Why are the melting and boiling points of air never given?
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.
Does carbon dioxide or water have a hogher melting point?
The melting point for carbon dioxide is 108.4 degrees Fahrenheit. The melting point for water is 32 degrees Fahrenheit.
Which has the higher melting point sulfur dioxide or carbon dioxide?
SO2
What gas is produced if you blow carbon dioxide in boiling water?
The gas that is produced if you blow carbon dioxide in boiling water is carbonic gas (H2CO3).
Why does boiling remove carbon dioxide from antacid mixture?
Carbon dioxide has a higher boiling point, so it gets released from the mixture before the other components.
What is the physical state of carbon dioxide at 25 degrees celsius?
25 deg. Celsius is about "room temperature," and assuming normal pressure (1atm) carbon dioxide is a gas.
Why might you expect silicon dioxide and carbon dioxide to have similar melting and boling points?
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.
Would carbon dioxide have a higher boiling point than water and why?
No, carbon dioxide has a much lower boiling point than water. The boiling point is the temperature at which a substance changes phases from a solid to a liquid. Carbon dioxide is a gas at room temperature, while water is found primarily in liquid form at room temperature. Therefore, at 78 degrees F, carbon dioxide is above its boiling point while water is below its boiling point.
Do elements compounds and mixtures have fix melting and boiling point?
Yes, elements have fixed melting points; but some exceptions are with the elements having allotropes (as carbon, sulfur, phosphorous, etc.) - each allotrope has a specific melting point.
What is the melting and boiling point of carbon-14?
The melting point of carbon is 3 500-4 000 0C in an inert atmosphere and at very high pressure. The boiling point may be a little higher. These data are unsure because carbon can sublime and measurements are difficult and probable inconclusive.
What is the boiling point for carbon dioxide gas?
Seung Jun is god
How you can measure the boiling point or melting point of carbon?
At high pressure and an inert atmosphere.
