Boiled water has less oxygen than unboiled water because the boiling process drives off dissolved gases, including oxygen.
nope sorry who ever does not know this is riri. and if you don't know what riri is find out! jajajaja
Cold water can hold more dissolved oxygen than hot water. This is because the solubility of oxygen in water decreases as the temperature increases. Therefore, cold water has the ability to hold more oxygen than hot water.
Oxygen is generally more soluble in fresh water compared to salt water. This is because the presence of salts in salt water reduces the solubility of gases like oxygen. Additionally, temperature and pressure also play a role in determining the solubility of oxygen in water.
Stream water typically has more oxygen because it flows constantly, allowing more oxygen from the air to dissolve into the water. In contrast, pond water is stagnant and can become depleted in oxygen over time due to limited exchange with the atmosphere.
Flowing water generally has more dissolved oxygen than still water because moving water allows more oxygen to be absorbed from the air. Still water can become depleted of oxygen over time due to lack of replenishment, especially in stagnant or enclosed areas.
No because boiled water has lost weight due to evaporation
Boiling water provides a health benefit only if the water is contaminated with bacteria or virus. Boiling for a few minutes will kill disease organisms, as will treatment with "water purification" tablets containing iodine or chlorine. Boiled water has no essentially different chemical composition compared to the same water unboiled.
No,boiling water does not have oxygen . Cold water molecules move slowly meaning there is space between the molecules for more oxygen to dissolve. Hot water molecules move rapidly meaning the space between the water molecules is less avalible for the oxygen molecues to dissolve into.
a cup of water that is boiled since it gives more heat.
yes it can
No. There is more oxygen in deeper water.
For water to be used it must be boiled to 100 degrees Celsius and boiled for more than a minute.
Nothing will happen to iron in oil. You may be thinking of the standard rusting experiment where one of the tubes contains an iron nail in boiled water sealed with oil. The purpose of this tube is to show that iron needs oxygen to rust. The boiled water does not contain dissolved oxygen and the oil prevents more from entering from the air.
When hydrogen peroxide is mixed with boiled water, the hydrogen peroxide will decompose into water and oxygen gas. The heat from the boiled water can accelerate this decomposition reaction, causing the hydrogen peroxide to break down more quickly. This reaction is exothermic, meaning it releases heat energy as the oxygen gas is produced.
Freshwater has more oxygen than salt water but oxygen is more solublein fresh water.

Oxygen is more soluble in fresh water than it is in sea water, therefore there is more dissolved oxygen in river water than sea water.
