can the boiling point of a element be negative??

Question

I have read in a book its given the boiling point of nitrogen is -195.8 C

Answer 1

Depends on the scale. The std temperature is kelvin. Nothing can exist below 0°C K as this is absolute zero.

You are talking about °C. The answer is definitely. The definition of boiling point is were a molecule/element goes from liquid to gas. If elements or compounds couldn't have negative boiling points then no gas could exist in the upper atmosphere or over the poles.

Some examples of pure elements that are not diatomic. like N2 are the noble gases. They have the following boiling points

Helium -269°C
Neon -246°C
Argon -186°C
Krypton -153°C
Xenon -107°C
Radon -65°C

Hope this helps:)

Answer 2

Boiling Point Of All Elements

Answer 3

Nitrogen is a gas At room temp, that low boiling factor makes this is a gas at room temp, it would help to look at boiling factor because of the fact the temp necessary to bypass from a ligiud to gas. So something smaller than -196 would be a liquid as quickly as the temp reaches -196 it is going to a gas. i'm hoping this permits you already know.

Answer 4

Yes There are a lot of eelemnts which are gas at room temperature . All the nobles gases He, Ne and oxygen is also a gas

Answer 5

ya man in centigrade scale all the gases have negative boiling points and all the liquids have negative melting points

Answer 6

Yes, you can check the boilig points on the PT.

Answer 7

Yez Dude Yez i depends upon the substance..................Negative temperatures are Wel........Temperatures itself...........Take the case of Glass Solid Glass is infact a liquid................B amazed to find out such facts...............in CHEMISTRY...

Answer 8

Of course it can.
