Does oil prevent water evaporation?
Oil evaporates very slowly. Oil doesn't mix with water, and most oils are less dense than water. So oil floats on top of water, and usually makes a very thin layer, covering all the water you have, or else it spreads out until the oil layer is just one or two molecules thick and you run out of oil. When the oil is covering the water, it prevents water molecules from evaporating, just like putting a lid on a jar.
Why does a balloon filled with helium gas rises up in the air?
helium is lighter that air so rises above the air. similar to oil rising above water.
Why does a light ray bend when it travels from air to water?
Air and water have different refractory periods, meaning that light rays are "bent" differently in air and water. This characteristic is found in all materials light can pass through (oil, glass, etc.) so light bends when it travels between substances all the time.
Why oil floating in water?
Oil density of water is lower.
Why is oil put on top of boiled water?
Well, if a nail was placed in the water, to prevent rust. Boiled water has no air and oil and water cannot mix so the oil stops any air getting in.
Why is sodium put in oil?
Sodium is very reactive in water. Thus to prevent it from reacting with air and water, it is stored in oil.
How are alkaline metals stored?
They are submerged in kerosene or other oil solutions to prevent them from reacting with the water vapor in the air and combusting.
Why oil the k and n air filter?
The oil traps small dirt particles from entering engine.
Why are alkali metals stored in oil and kerosene?
They are so reactive they even react with the moisture in the air. Storing under oil prevents this.
What is the difference between Over-Balance and UnderBalance?
The amount of pressure in the wellbore that exceeds the pressure of fluids in the formation;This excess pressure is needed to prevent reservoir fluids (oil, gas, water) from entering the wellbore
What best explains the U.S. motivation for entering the Persian Gulf War?
To prevent Iraq from conquering its oil-rich neighbors
What will happen if you put oil on a flower?
Oil would prevent the plant from taking in air. The plant would die. When a plant is dormant, you can put dormant oil on them to kill insects.
What are facts about soduim?
It is a Alkali earth metal and is highly reactive to water, if dropped in water, it will explode and light in fire immediately. It is very soft and is stored in oil or kerosene to prevent it from reacting with the water molecules in the air.
Does mineral oil prevent rust?
yes, because when you put oil on bearing or hardware the water does not make the metal wet.THe water just slides off.
What will happen in the iron nail after 3 days if its exposed to oil.?
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.
How do you store alkali metals?
Alkali meatls are stored in oil to stop it from mixing with the moisture in the air.Because Alkali metals are highly flammble in moist air.
