Question

The melting point of Fluorine is -219 C while that of bromine is- 7.3 C. Given that information, how would you estimate the melting point of chlorine?

Answer 1

Take the average?

Explanation:

Well, let's take the average using absolute temperature:

`((54+265.7)*K)/2` `=` `159.9*K`

`=-113` `""^@C`.

The literature melting point of chlorine is `-101.5` `""^@C`, so this estimate is a good first approximation.
