Group Title
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.

It 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.

the cohesive force is stronger than adhesive force .... the intermolecular bond between water molecule is stronger than intermolecular bond between surface and water.

On 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

I 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

surfaces matter .. for some surface the water molecule does not form dome ... while for some surfaces forms smaller dome.
