Why don't fish live very long in water that has been boiled and brought back to room temperature?

Fish can't survive in boiled water because they are cold-blooded animals. Their bodies adapt on the temperature of their environments. Another reason is, the temperature of boiled water is beyond the normal temperature of their environment.
a2. Ahem, I think the Q concerned boiled water, not boiling water. The outcome is the same as above, but in this case, because even if the water was cooled again, it would be quite deficient in dissolved air. From a fishes point of view that is.

The boiling process removes the air that was dissolved in the water. Upon cooling the water is void of its usual air content, hence, the fish drown.

∙ 15y agoBoiling water drives off the dissolved oxygen fish live on. Some fish can live in it--lungfishes, walking catfishes, and anabantids like bettas and gouramis come to mind. All those fish are airbreathers. Fish that are strictly gill-breathers will die in boiled water.

Will iron nail rust in boiled water?
Iron must be in contact with oxygen, water (and dissolved ions) to rust. So if it was in boiled water there would be no oxygen present and as long as no oxygen was allowed to dissolve back into the water, for example if a layer of oil was on top of the water, then the iron nail would not rust.
Will air bubbles appear if boiled water is reheated?
The bubbles are water vapour (ie steam) bubbles, not air. Therefore any heating of water back up to boiling point will renew the process of water vapour bubbles occurring.
Is boiling water irreversible?
From a thermodynamics standpoint, it depends how the process is carried out. If the system (the water) and the surroundings remain close to equilibrium during the entire process then the water boils reversibly. So if the change in temperature is approximately zero throughout the process and the process takes an infinitely long amount of time to carry out you can reversibly boil water.If you were asking whether water vapor can turn back into liquid water, then yes the process of turning water into water vapor is reversible.
Does temperature increase or decrease when going from gas to solid?
The temperature decreases as the gas (vapour) turns back into a liquid. For instance, the hot water vapour from a kettle can be cooled so as to condense back into water.
What is the process that involves water vapor in the atmosphere becoming liquid water?
It is called Condensation. its when warm water vapor hits the cool air and the temperature drops. causing it to convert back to a liquid.
How made distilled water?
water is boiled - the steam is captured and cooled back to water. Will remove heavy particulates and other elements.
Will iron nail rust in boiled water?
Iron must be in contact with oxygen, water (and dissolved ions) to rust. So if it was in boiled water there would be no oxygen present and as long as no oxygen was allowed to dissolve back into the water, for example if a layer of oil was on top of the water, then the iron nail would not rust.
When water is boiled is it a chemical or physical change?
Boiling is a physical phenomenon, a change of phase.
Relationship of temperature of boiling water and temperature of steam?
In the case where heat is being added to generate steam from a container of water, as long as there is water still in the container, the temperature remains constant. It takes energy for water to change state into steam and all of the heat added goes to performing this task so the temperature stays the same, 212 degF (100 degC) at atmospheric pressure. While the water is boiling, the steam is "saturated," meaning any loss of heat would cause some of the steam to condense back into water. Once all of the water has been boiled and changed state, any additional heat supplied will cause the temperature to increase and the steam is "superheated," that is above its saturation temperature.
What is presurised cooing system?
All auto cooling systems are pressurized. The radiator cap holds the pressure in the system at about 15Lbs. The reason for it is it causes the boiling point of water to be at a higher temperature so the water doesn't boil away as easily. The big white tank beside the radiator allows boiled water STEAM to stay in the cooling system and condense back to water and return back into the radiator as it cools. Champ390
How can salt be separated from saltwater?
You boil the saltwater, collect the steam and have it cool back into water in a different container, and whats left after all the water has been boiled, is the salt.
What happens to the temperature of water after an ice cube fully melts?
IT slowly increases back to room temperature
What temperature does it have to be to put your fish back in pond?
it depends on what type of fish.a goldfish has to be in room temperature water.
What is an distilled water?
ordinary water is just boiled to vapor and recollected to filter out impurities
If the water reaches a maximum temperature of 26.4 degrees celsius how many joules of heat were released by the pebble?
Go back and find out how much water there was, and what temperature it started out. Then come back with that information and we can answer your question.
How is drinking water made from sea water by distillation?
When sea water is boiled only the water turns to steam, the salt is left behind. Then when the steam condenses back into liquid you get clean, distilled water that is safe, if a bit bland to drink.
Does temperature increase or decrease when going from liquid to gas?
The temperature decreases as the gas (vapour) turns back into a liquid. For instance, the hot water vapour from a kettle can be cooled so as to condense back into water.
