He lewis structure of clf shows that has nonbonding electron pairs.

The Lewis structure of clf shows that cl has 0 pairs of nonbonding electrons and f has 0 pairs of nonbonding electrons. There are fourteen valence electrons, and once these electrons are paired, there are no electrons left that are not bonding.

Well, both latitude and intensity of light affect temperature because, the higher the light intensity, the higher the temperature and since latitude is the measure of how close you are to the equator, then the closer to the equator you are, the higher the temperature is.
