A drop of water placed on a smooth, dry surface will form a domeshaped droplet instead of flowing outward in different directions. Which of these best explains this observation?
A. The bonds between hydrogen and oxygen atoms are very strong. <<My Answer
B. The electrons in the atoms attract the electrons in the other atoms.
C. Water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.
D. Water molecules near the surface produce more buoyant force than water molecules within the liquid.

Best ResponseYou've already chosen the best response.2It is due to surface tension,they have to occupy minimum area,that is related with buoyant force,hence D. A,C&B are potinless options.

Best ResponseYou've already chosen the best response.0the cohesive force is stronger than adhesive force .... the intermolecular bond between water molecule is stronger than intermolecular bond between surface and water.

Best ResponseYou've already chosen the best response.0On a waxy surface such as a leaf, Water adheres weakly to leaf and strongly to itself, so water clusters into drops. Surface tension gives them their nearspherical shape, because a sphere has the smallest possible surface area to volume ratio. Source http://en.wikipedia.org/wiki/Surface_tension

Best ResponseYou've already chosen the best response.0I have another quick question... A scientist adds heat to each of the following substances. Which will probably absorb the most heat before its temperature changes significantly? 50 g of solid copper 50 g of solid iron 50 g of liquid water<<My answer 50 g of sand
