The picture shows the average dissolved oxygen values of ocean surface waters. Describe the general trend of the sea surface oxygen as you move from the
equator toward the poles. Explain how this trend relates to the relationship
between the solubility of a gas in water and temperature.

Asample of silver (with work function ? = 4.52 ev) is exposed to an ultraviolet light source (? = 200 nm), which results in the ejection of photoelectrons. what changes will be observed if: silver is replaced with copper (? = 5.10 ev) more photoelectrons ejected no photoelectrons are emitted fewer photoelectrons ejected more energetic photoelectrons (on average) less energetic photoelectrons (on average)
