why bubles are formed?

bubles are formed because the air trapped b/w  the layers of water molecules surface out.due to surface tension of water, a thin film of water traps this water. that's how bubles are formed.

Flour doesnt dissolve in water, it forms a suspension- If something dissolves, it forms a clear solution.  The previous answer is correct, it shrinks due to the loss of air.

The first pressure plate is flat.\n\nThe second pressure plate is dimpled once for each bubble.\n\nIn each dimple of the second pressure plate is a very tiny vacuum hole so that the second layer of plastic is streached into the dimple from the pull of the vacuum.   This is the same as a golf ball dimple, only these dimples are larger and formed into the flat surface.\n\nOnce the dimples are formed with the vacuum of pulling the second layer of plastic into it. Both layers of plastic are fused together where there is not a dimple.

D. formation of micelles\n\nMicelles only form when the concentration of surfactant is greater than the critical micelle concentration (CMC).

The problem with having a true and reliable answer is that new evidence will change it later on.  For now, the best answer is that it formed from a protosolar disc of dust.\n\nSee source for details.

because white light is made up of many particles/waves of different wavelengths.  The bands aren't formed as in made, they're formed as in resolved or separated.  And they're seperated because when they bounce off of the interior angles of the prism they bounce at different angles, determined by their wavelength.

Probably carbon latice structures, like buckeyballs or nanotubes.  These could then contain the smaller compounds that are doing the desired work.

Formation of a cell wall is a characteristic feature of all plant cells.Its formation in angiosperms does not differ much from its formation in other plants cells.\n After the nuclear division is over (end of karyokinesis)only then the division of cytoplasm(cytokinesis) begins.\n A number of microtubules are laid across the original cell, equidistant from the two recently formed daughter nuclei. They fuse to form middle lamella.This is the first dividing boundery between the two cells. Deposition of cellulose now begins on this middle lamella from either side and the wall formation is completed. Thus, a cell wall in plant cells is by and large made up of a complex carbohydrate called cellulose and in between the two layers of cellulose there is a layer called middle lamella.It is like butter sandwich. Just as the layer of butter holds the two slices of bread together or just as the layer of cement holds two adjecent bricks together and forms a wall; like wise the middle lamella holds the cells together and helps to form a tissue.

Its due to some micro-organisms in the soil.\nTheir sporebags rupture on contact with water, and they enter the air.

No.....to burp is to expel gas from the stomach through the mouth.  If you have trapped gas it will find an exit out of your body.  It does not have to come out thru the mouth.

Water molecules attract each other. This is called cohesion. \nThe oxygen end of water has a negative charge and the hydrogen end has a positive charge. The hydrogens of one water molecule are attracted to the oxygen from other water molecules. This attractive force is what gives water its cohesive properties.\n\nSurface tension is the name we give to the cohesion of water molecules at the surface of a body of water. It is the reasons that water contracts in drops.\nWhat is happening? Each molecule in the water drop is attracted to the other water molecules in the drop. This causes the water to pull itself into a shape with the smallest amount of surface area, a sphere. All the water molecules on the surface of the bead are 'holding' each other together or creating surface tension.\n\nSurface tension allows water striders to 'skate' across the top of a pond. You can experiment with surface tension. Try floating a pin or a paperclip on the top if a glass of water. A metal pin or paper clip is heavier than water, but because of the surface tension the water is able to hold up the metal.

It could be that lol or it may be due to the bacteria that lives within the body of water, such as blue algae. :)

The air inside the baloon is compressed, because of its containmentt inside the stressed rubber. (You need to blow to fill a baloon). When the rubber is split, the air expands rapidly to equal the surrounding pressure. This rapid expansion propogates outward, causing tha bang.\n\nget it???\nplzz select as a best answer

There are gasses dissolved in the fluid. When you stretch the joint the volume increases and therefore the pressure in that volume decreases. This allows to gas to come out of the liquid. It makes a noise like opening a bottle of soft drink. This is also the same principle that gives divers the bends if they come up too quick. \nThere is a name for the law, it is to do with dissolving gasses in a liquid under pressure. I am suffering a mental block, err henry's law?? russels?? errr.. some plain name like that anyway

Because they started as gas/liquid, and round is the lowest energy state for a liquid.\n\nLike a raindrop.

They form basic oxides and hydroxides.  The elements themselves are not basic under any definition of "basic".
