oil does not mix with water, rather, it floats on water
this is because oil is less dense than water and they are immiscible solutions
Try it! Cooking oil will work well. It will be quite difficult to break the oil drop up if its only a small one. It may disappear at first, then it will float back to the surface.
Oil form an unstable dispersion.
The slt is dissolving into the water
because the cohesion of water molecules is less stronger than the adhesion of the water molecules
It depends on temperature. The warmer the liquid the faster diffusion occurs.
A drop of Dettol will get evenly distributed into water. The reason this happens is because that there is enough space between the particles of matter.
The spread of a drop of food dye throughout a glass of milk is called
the water is sweetened
When you put a drop of food coloring into a glass of water, the water will turn that color.
The food coloring will spread throughout the water and become homogeneous faster than it would in cold or warm water. The food coloring would also mix evenly with the water faster if you stirred the water after adding the food coloring. This happens because the molecules are moving faster when they are heated up stirred.
When you drop most things in water the object sinks and the water rises.
It will melt.
You would see the drop slowly spread out until eventually the entire glass of water would be colored.
The slt is dissolving into the water
A good question might be, "How long does it take a drop of food dye to color a glass of still water?"
Drop a drop of food dye in a glass of water and watch. The dye diffuses through out the water, weakening the dye and coloring the water.
lETTERS TOWARD THE CENTRE OF THE DROP WOULD APPEAR ENLARGED. dROP WORKS AS MAGNIFYING GLASS.
Yes it does due to the rapid temperature drop on the glass.
the stage is the small glass piece on the microscope.
