Answer:
See below
Step-by-step explanation:
There are several reasons why the water in a stream may contain more dissolved oxygen than the water in your hous
e:
- It is exposed to the atmosphere, so it can absorb oxygen from the air. Tap water sits in pipes, away from the atmosphere.
- It is in motion, so turbulence brings more water to the surface and in contact with the atmosphere. Tap water is usually stagnant (not moving).
- It is colder than tap water. The solubility of oxygen in water decreases as temperature increases,
- Plant life in the stream releases oxygen into the water.
