The answer to this question is A. Humidity.. because humitity causes steam
Answer:
The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. Dispersion forces are present between any two molecules (even polar molecules) when they are almost touching.
Thus <em>PROTON movement causes partial positive & negative charges creating
</em>
<em>attraction</em> will be crrt

Explanation:
Electronegativity is the ability of an atom in a molecule to attract the shared electrons of a covalent bond towards itself. Electronegativity is a trend that increases across the period and decreases down the group in the periodic table.
All the compounds listed are halides of phosphorus. The electronegativity of halogens decrease in the order; F> Cl> Br > I. Hence F has the greatest electronegativity in the group. It decreases as atomic and ionic radius increases.
As the electronegativity of the halogen atom decreases, the electron pair on the halogen atom lie closer to the central phosphorus atom hence the repulsion between electrons increases and so does the bond angle increase likewise.
