Normally red blood cells look like flat disk, witch is compressed in the center. So that they have more surface area when they get exposed to oxygenated air from alveoli and secondly they can get folded, when they squeeze through capillaries, witch are smaller than the size of red blood cells. When we put them in the distilled water, they will get swollen, like a boll, as water will enter the cells due to higher oncotic (osmotic, you can say) pressure inside the cells.
When red blood cells are immersed in water, they will burst. This is because the water has a much greater water potential than the cell cytoplasm, so water will transfer into the cell by osmosis. When this happens with red blood cells, it is called haemolysis.
When distilled water and blood (my class did it with sheep's blood) are mixed, the result is that the blood will disappear.
If they are centrifuged and distilled water is added, they will burst immediately
The distilled water is a hypotonic environment.
I think its osmosis because the water potential in the distilled water is higher than in the red blood cell. Henceforth, water would move into the cell by osmosis. But, I don't think the cell will be diluted because it will swell and eventually haemolysis will occur.
The red blood cell would swell because more water would pass in than it would pass out.
no

no
When it is in a hypotonic solution such as distilled water.
You can certainly expect the blood cells to stain the water as their cell membranes rupture from being in a hypotonic solution. The term that describes this is "To lyse". Blood cells lyse in distilled water.
yes with distilled water
When a red blood cell is placed in distilled water it will swell and burst. This is a physical change.
because of osmosis it would get fatter and fatter with water till it burst. aww.
Your question is confusing, did you mean "distilled" water? Your body & cells live and function not in a pure water environment, but water with several electrolytes in specific concentrations: sodium, potassium, calcium, chloride and several others. If you placed red blood cells into pure water (distilled water) that did not have any of the electrolytes mentioned above, the distilled water would enter the blood cells through the process of osmosis. The basic idea of osmosis is that if there is a chemical gradient and a permeable membrane separating this gradient, there will be a transfer of water trying to reach an equillibrium. The solution in your red blood cells would be hyperosmotic compared to the distilled water. The cell membranes are semi-permeable, and would allow some of the distilled water to enter the cell, trying to balance the osmolarity. The effect would be that the red blood cells would swell with distilled water and likely burst--like an over-filled water balloon. If enough red blood cells were to pop, they could release enough electrolytes into the distilled water to keep other red blood cells from swelling and popping.
