What is the boiling point of helium in celsius?
Helium (He)Boiling points: 4.22 K, −268.93 °C, −452.07 °F
What are the boiling and freezing points of helium?
4.22 k, −268.93 °c, −452.07 °f
How do the boiling points of the noble gases change as you go down?
The boiling points of noble gases increases down a group.
What is the melting and boiling points of helium in dgrees C?
The melting point of helium is 1.15 K and its boiling point is 4.22 K. So in oC they would be: Melting Point: 1.15 - 273.15 = -272.00 oC Boiling Point: 4.22 - 273.15 - 268.93 oC
Are boiling points and freezing points checimal changes?
No, boiling points and freezing points are physical constants that are unique to each substance. The phase change between solid and liquid and between liquid and gas is a physical change.

What is the boiling point of noble gas?
"Noble gas" is not a single thing, it is a category of elements. Noble gases compose the rightmost column of the Periodic table: Helium, Neon, Argon, Krypton, Xenon, and Radon. All are gaseous at any standard temperature ranges. Boiling points (in Centigrade): Helium: -269 Neon: -246 Argon: -185 Krypton: -153 Xenon: -108 Radon: -61
What element has the Lowest boiling point?
Of the gases on the periodic table, I don't think any have boiling points between 0oC and 25oC, so all the elements listed as gases on the periodic table have boiling points below 0oC. Hydrogen, oxygen, nitrogen, fluorine, chlorine, helium, neon, argon, krypton, xenon, radon Of course Ununoctium is predicted to be a gas, but with only 3 atoms ever made nobody really knows for sure what its melting point is so I left it off the list.
Comment on the trend in the boiling points of the Noble gas elements and why do boiling points vary in this manner.?
According to the trend, the boiling point of the noble gases decreases down the group, as you know the number of shells increases down the group but the number of valency electrons remains the same. the further away the nucleus is to the outer electron, less the attraction. Therefore, resulting in less energy needed to change the state of the element which brings us to the conclusion of decrease in the boiling points of noble gases down the group. I hope it helps Cheers mate !

Why does chlorine have a higher boiling point than krypton?
To determine why chlorine's melting point (-100.98) is higher than krypton's melting point (-157.2), you must look at the electron configuration of the elements. 36Kr: [Ar]4s23d104p6, and 17Cl: [Ne]3s23p5. There is a trend in the periodic table that states that elements with paired electrons in the electron orbitals will have extremely low melting points (why all noble-gases have low melting points). So since krypton is a noble-gas, it has every electron orbital filled, forming an octet, therefore having a lower melting point. Chlorine, has a 3p5 orbital and therefore not completing the octet, or paired p-orbital, therefore having a higher melting point.
Does the amount of water change the boiling or freezing point of water?
No, quantity does not influence any temperature like boiling or freezing points of any substance.
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.
What are the freezing and boiling points of water on the Fahrenheit scale?
32 freezing, 212 boiling - at sea level. Temps change as air pressure changes.
