Why phosphorous kept in immersed water?
Phosphorus is kept immersed in water to prevent its reaction with oxygen in the air, which can cause it to ignite spontaneously. Keeping phosphorus submerged in water helps to maintain its stability and prevent any potential hazards.
What changes take place when water is left in an open container in a closed container?
When water is left in an open container, it can evaporate due to exposure to air. In a closed container, the water vapor will eventually reach equilibrium with the liquid water, leading to increased humidity inside the container. If the container is completely sealed, no water vapor can escape, leading to a buildup of humidity over time.
Why keep pH glass electrode immersed in water before and after use?
Keeping the pH glass electrode immersed in water before and after use helps prevent the electrode from drying out, which can affect its accuracy and performance. It also helps to maintain the hydration level of the electrode, ensuring proper functioning and stability during measurements.
How can a container hold water?
A container is able to hold water because the container's atoms are bonded closer together than each water molecule's total size. This prevents the water molecules from sliding out between the container's atoms, thereby holding the water inside.
How do you keep food cold in ice water?
To keep food cold in ice water, make sure the food is in a sealed container or bag to prevent water seepage. Place the container in a larger container filled with ice water, ensuring the water level stays above the food level to maintain cold temperatures. Replace melted ice with fresh ice as needed to maintain the cold temperature.
If a stone is immersed in a container of water the water level?

How would you find the volume of a stone by using water displacement?
Place a rock in a container, add water, and record the volume.Pour an unknown amount of water into a glass container, add the rock, and note the water level; the unknown amount of water plus the weight of the rock is the volume of the rock.Pour a known amount of water into a glass container, add the rock, and note the new water level; the difference in water levels is the volume of the rock.Water displacement will not work.
How do you find the weight of the equal volume of water that buoys up the immersed stone when it is immersed?
you can use a 300ml graduated cylinder water,3different objects
Why does a person lift a heavy stone immersed in water as compared to air?
If the question is asking "for what reason would a person lift a heavy stone immersed in water as opposed to air?" then the answer is buoyancy. When immersed in water there will be an upward force on the bottom of the stone due to the volume of water it has displaced. This upward force will make the stone seem lighter to the person lifting it by decreasing the amount of force they need to exert to lift it.
What are the 4 steps in order for the water displacement method?
Fill a container with water. Submerge the object in the water, making sure it is fully immersed. Collect the water that is displaced by the object in a separate container. Measure the volume of this displaced water, which is equal to the volume of the object.
Why is it easier to lift a heavy stone when fully immersed in water?
Because an object immersed in water is buoyed upward by a force equal to the weight of the displaced water, so the stone's net weight in water is less than it is in air, by a difference of roughly 62 pounds for each cubic foot of its volume.
How do you find the volume of a or an irregular shape?
To find the volume of an irregular shape it is immersed in water and the volume of water displaced is the volume of the shape.A can with a hole high in the side can be filled until the water is exactly at the hole ie over filled and no more water is running out.A measuring container is positioned to catch any overflow of water.The object is immersed in the can and the water is caught in the measuring device.The volume of water collected = the volume of the object.In science cans are made with a spout on one side for this purpose.
What level can you use the water stone to evolve lombre?
any level, just let lombre hold the water stone and then train it to the next level
What is the optimal method for measuring the water level in a container using a hose?
The optimal method for measuring water level in a container using a hose is to attach a clear tube to the hose and submerge the open end of the tube into the water. The water level in the container will rise in the tube, allowing you to easily read and measure the height of the water.
What level does staryu evolve on emerald?
It evolves by use of a water stone, level has nothing to do with it.
What level lombre evolve in emerald?
You use a WATER STONE on Lombre to get Ludicolo.
Can Vaporeon evolve?
Vaporeon does not evolve. It is a top-tier Water evolution of an Eevee, attained by using a Water Stone on an Eevee.
