If the added water drastically changed the current water temperature, the fish could have gone under shock. The only other thing I can think of, was the fish might have been in the process of expiring at the same time you were adding the water just by coincidence.
Because while the water is hot with the oil, chemicals that are in the sugar causes it to bubble.
it might be a bent piton rod if you or water or somthing into the engine
By adding salt it means that you are adding an impurity into the water. Impurities can lower the boiling point, while increasing its melting point.
Pouring acid into water while stirring helps to dilute and disperse the acid gradually, reducing the likelihood of splashing or causing a violent reaction. Adding water to acid could cause a sudden release of heat, which can cause the mixture to splash and potentially result in burns or an explosion.
This is called hydration energy (heat).
yes, but i couldn't tell you the mechanics of it.
Typically, water will dilute a solution. However, that said, it also depends what you're adding the water to, ex. adding water to oil won't dilute in the same ways.
It might cause a dry mouth and so make you want to drink a bit more. You do not need to make a special effort to drink more water while taking it.
Physical change can occur when energy is added or removed. For example, adding heat energy can cause water to change from a solid to a liquid (melting), while removing heat energy can cause water to change from a liquid to a solid (freezing). These changes do not alter the chemical composition of the substance.
Well, it depends on the appliance. Water with electricity is a bad idea and if you it strikes you while you have water on yourself or if an appliance is in water and plugged in, if you touch the water it may shock you and even kill you. A fire may also start and the appliance might no longer work.
Correct. When diluting sulfuric acid, it should be added slowly to water while stirring constantly. This is to prevent excessive heat generation from the exothermic reaction that occurs when concentrated sulfuric acid is mixed with water, which could cause the solution to splatter or boil dangerously.
You can do a water change while it is cycling, but that might slow down the process.
