# 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?

Take the average?

#### Explanation:

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

$\frac{\left(54 + 265.7\right) \cdot K}{2}$ $=$ $159.9 \cdot K$

$= - 113$ ""^@C.

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