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 . 9B b. If the maximum amount of 14 mg of oxygen was added to 1 liter of water. Dissolved Oxygen (mg) 100% 100% 25% Temperature (oC) 0 -15 30 Draw a graph with the oxygen dissolved in mg % (100 to 0) vertically, and temperature in oC (-30 to 30) horizontally.
