phosphorous is kept immersed in water because it reacts with air.
Sodium is a metal that is commonly kept immersed in kerosene for storing because it reacts violently with water and oxygen in the air. Placing it in kerosene helps prevent these reactions and keeps the metal stable.
White phosphorus should be kept in water or under a layer of oil to prevent its exposure to air, as it is highly reactive and can spontaneously ignite upon contact with oxygen. Storing it submerged helps to reduce the risk of accidental fires and exposure to air. Additionally, white phosphorus can release toxic fumes, and storing it in water can help to contain these fumes and prevent them from dispersing.
Sodium reacts violently with water, releasing hydrogen gas and forming sodium hydroxide. When sodium is kept immersed in kerosene oil, it is isolated from water, preventing the reaction from occurring. Kerosene oil acts as a barrier to keep oxygen away from the sodium, further preventing combustion.
White phosphorus is a highly reactive, pyrophoric substance that ignites spontaneously in air. It is stored underwater to prevent contact with oxygen and reduce the risk of ignition. White phosphorus can react violently with oxygen, leading to fires and potential harm.

Because is reacts with water causing hydrogen to be released and catch fire. Na + H2O = NaOH + H also it will also float on water having a density of 0.98 g/cm^3
Phosphorous
Sodium is kept immersed in kerosene because it reacts so vigorously that they catch fire when kept in the open. Hence to protect them and to prevent accidental fires, they are kept immersed in kerosene oil.
White phosphorus is a highly reactive, pyrophoric substance that ignites spontaneously in air. It is stored underwater to prevent contact with oxygen and reduce the risk of ignition. White phosphorus can react violently with oxygen, leading to fires and potential harm.
When an object is immersed in water, it means it is completely surrounded or covered by the water.

I immersed the boiled egg in cold water to cool it down
you can use a 300ml graduated cylinder water,3different objects
