Question

Why oxygen solubility decreases as temperature increases?

Answer 1

$\huge\mathfrak\red{Heya\:..!}$

Increased temperature causes an increase in kinetic energy. The higher kinetic energy causes more motion in the gas molecules which break intermolecular bonds and escape from solution. ... As the temperature increases, the solubility of a gas decreases as shown by the downward trend in the graph.

Answer 2

the solibility of allmost all gasses decrease with increasing temperature .you can see effect when you heat water long before it boils , little bubbles of air form, as air comes out of solutions .
