Hey ! For all those who are wandering why this happens here's the answer .It happens for three reasons .1 .Osmostic concentration : Osmosis occurs from low osmotic concentration to high osmotic concentration ( ie : Hypotonic to Hypertonic ) .2 .Free energy : Osmosis occurs from mediums of high free energy to low free energy .3 .Entropy : Osmosis occurs from regions of low entropy to high entropy . I hope this was a helpful explanation ! Enjoy your lab session :D

If A spherical ball is immersed in water contained in a vertical cylinder how do you Calculate the rise in the level of the water?
If the sphere has radius r and the cylinder has radius d then the rise in water level will be 4/3(pi r3) / (pi d2) which simplifies to (4 r3) / (3 d2).
What is water displacement?
Water displacement is simply when something (e.g. a block) is put into water, and the water level rises. This is because the block is taking up space, and the water has to move somewhere, and the only place to go is up.
What is the alternate rise and fall in the level of sea water?
The rise and fall is the tides.
Why should you measure a liquid at the bottom of the meniscus?
The liquid molecules are more strongly attracted to the graduated cylinder than to each other. This causes the liquid to rise up on the sides of the graduated cylinder. Therefore it is important to read the line, even with the center of the meniscus, and at the bottom of the meniscus to accurately measure the volume of a liquid in the graduated cylinder. If you are still a bit confused I also found some information at this website: http://chemistry.about.com/od/chemistrylabexperiments/qt/meniscus.htm
What will happen if ice in kept in glass of water does the level of water will rise or not?
yes, becuse when ice melts it becoms water.Answer:When ice is added to a glass of water the level will rise. After that, as the ice melts the level will decline. When water freezes it expands, so when it thaws back to a liquid it shrinks.
Which property of marbles causes the water level to rise when they are put in a graduated cylinder?
The fact that they are waterproof. Partly but they take space in the water and as a result water is displaced and rises.

When a rock is placed in a graducated cylinder containing water the height of the water will?
The height of the water will rise a level equal to the volume of the rock.
A sphere of radius 2 cm is dropped in to a cylinder of radius 4 cm which cotain of water the rise in the level of water is?
0.6 cm
When the anchor is thrown into the water will the water level in the pool drop or rise?
The anchor displaces water and the water level will rise.
What tools would you use t measure volume and mass of a solid?
To measure the volume of a solid, you would place the solid in a graduated cylinder or beaker (depending on the size of the solid) with a recorded volume of water. After putting the solid in the water, the water will rise, and subtracting the original volume from the final volume will give you the volume of the solid. Ex. Put a block in a graduated cylinder with 50 mL of water and the level rises to 75 mL. Volume=75-50=25 mL To determine the mass of the solid, you would simply mass it on a balance or scale.
How will you find the volume of stone using measuring cylinder?
The volume of the stone is measured by displacement. Water is put into the measuring cylinder to a noted mark. The stone is placed in the cylinder and the water level will rise. The difference between the two levels is the volume in ml of the stone.
Which tool is used to find the volume of a liquid?
Multiplying the height, depth and width of the cube together (which in a true cube will be identical to the length of one side cubed) will give you the volume of that cube. The units will be whatever units the lengths were in, cubed. For example, a cube which has sides each of length 2 metres is worked out as: 2m x 2m x 2m = 8m3 Which is the same as: 23 = 8m3
How to find the volume of an irregular shape?
To find the volume of an irregular shape, you need to use the water displacement method. If the object can fit into a graduated cylinder, fill the cylinder with enough water to adequately cover the object, but don't put the object inside the cylinder yet. Record the amount of water in the cylinder. Carefully drop the object into the cylinder. This will cause a rise in the water in the cylinder. Record this second volume. Subtract the first volume from the second volume, and the difference is the volume of the irregular object. For larger objects, use an overflow can.
What is the alternate rise and fall in the level of sea water?
The rise and fall is the tides.
If you have a 100.0-mL graduated cylinder containing 50.0 mL of water. You carefully place a 129-g piece of brass of density 8.56 gmL into the water. What is the final volume reading in the cylinder?
The water will rise by the volume of the brass: volume = mass/density = 129g / 8.56 g/ml ≈ 15.1 ml → final reading ≈ 50.0 ml + 15.1 ml = 65.1 ml
