Different amounts of oxygen can be dissolved in water as the
temperature of the water changes. The maximum amount of
oxygen is 14 mg/liters at the coldest temperature of 0oC. At 35 oC
about 7mg/liters can be dissolved.
a. Assume the decrease in temperature in relation to
dissolved oxygen for temperatures 0 to 35. Draw the
graph under this assumption with domain from 0 to
35 oC, and range from 5 to 15 mg/liters .
