Check the images carefully. Now let’s see which option is correct.1. The tea in the three glasses has the same amount of heat. --- Incorrect. They would have different amount of heat. Glass L will have maximum, because it has more tea, and Glass M will have minimum.2. The tea in the three glasses is of the same temperature. --- Correct. The temperature is 75 Degrees in all three glasses.3. There is more heat in Glass L than in Glass M. --- Correct.4. There is less heat in Glass N than in Glass M. --- Incorrect. Glass N will have more heat than in Glass M.So, Option B is the right answer.

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


Won’t there be an increase of CO 2 if the oxygen level goes down and the fishes respire?!??!

Ans 1:

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 2:

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

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 4:

Class : Class 9
The concentration of oxygen decreases in warm water as the solubility of gases in water decreases as the temperature increases.
