I think the answer is A, is that correct?
i think renee u r wrong...
ya its right ..a option is correct u r right...according to http://answers.yahoo.com/question/index?qid=20100706102709AAqiYmG
Well, My second choice was D...
i don't know the reason
Nope a is not correct, it's D. I'm thinking of a proper explanation
ash can u explain it..
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 near-spherical shape, because a sphere has the smallest possible surface area to volume ratio. Source- http://en.wikipedia.org/wiki/Surface_tension
Ahhh, okay. I gotcha! :)
Thanks u guys!
ok. concept of 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<
if A had talked about hydrogen bond, i would have gone for A.
okay, will do
hydrogen bonds are merely simple attractions,you cant relate them with shape of a molecule
thanks again everyone!
surfaces matter .. for some surface the water molecule does not form dome ... while for some surfaces forms smaller dome.
and yes thhe answer to your second question is water,since it has thehighest specific heat capacity
ohh thanks :)
u don't have to follow the link then...
did you get both answer right ?
