13.4: Effects of Temperature and Pressure on Solubility

Because of the reduced solubility of (O_2) at higher temperatures (Figure (PageIndex{2})), the warmer water contains less dissolved oxygen than the water did when it entered the plant. Fish and other aquatic organisms that need dissolved oxygen to live can literally suffocate if the oxygen concentration of their habitat is too low.
