Read the passage below and choose the right answer to the following question (choices are 80 degrees fahrenheit or 70 degrees fahrenheit ):

Warm water cant hold as much dissolved oxygen as cool water, so an increase in the temperature of water decreases the amount of oxygen it contains.


Mary is taking measurements of the amount of oxygen in samples of water. If she measured the total levels of dissolved oxygen in a sample at 70 degrees fahrenheit and compared it to a sample at 80 degrees fahrenheit, which would contain less dissolved oxygen 80 degrees fahrenheit or 70 degrees fahrenheit?
