A person put warm water in an aquarium, thinking that the fish would be more comfortable in it. However, the fish died. What can be the reason for this?
A The concentration of oxygen decreases in warm water.
B The concentration of carbon dioxide increases in warm water.
C Fish cannot bear the extreme heat of the water.
D All of these
Wonât there be an increase of CO 2 if the oxygen level goes down and the fishes respire?!??!
Ans 1:

The concentration of oxygen decreases in warm water as the solubility of gases in water decreases as the temperature increases.
Ans 2:
Class : Class 10
Yes, but the concentration of oxygen does not decrease in warm water. The fish will die because they cannot bear the extreme heat.
Ans 3:
Class : Class 10
The solubility of ALL gases decrease when the temperature increases. As you can read , a person put warm water (and not boiling or too hot) for the fish to bear.

Ans 5:
Class : Class 7
Yes the concentration of oxygen decreases and the fish cannot bear the heat. I think options are wrong. It should be both B and C
