Answer:
The solubility of oxygen gas increases with colder temperature
Explanations:
Trouts is a freshwater fish that belongs to the salmon family. They are commonly found in cold streams due to the availability of more oxygen in cold waters.
As the temperature of water increases, the water begins to warm off causing the oxygen rate to reduce and dissipate causing trout to feel stressed even before the oxygen reaches the lethal level.
Based on the explanation above, we can conclude that trout are found in cold streams because the solubility of oxygen gas increases with colder temperature
