if the temperature of water increase or if hot water is added to water at normal temperature, what will happen to amount of dissolved oxygen in it? will it increse or decrease?
-
Solubility of gasses deceases with increase in temperature. So solubility of dissolved oxygen will decrease when u heat water or when hot water is mixed with cold.
Lets be much clear about the concept....
This gas solubility relationship can be remembered if you think about what happens to a "soda pop" as it stands around for awhile at room temperature. The taste is very "flat" since more of the "tangy" carbon dioxide bubbles have escaped. Boiled water also tastes "flat" because all of the oxygen gas has been removed by heating.
