Question
Water has the following unique combination of qualities:
A) H2o molecules form hydrogen bonds with each other. They are cohesive.
B) H20 molecules like to bond with ions or other charged molecules. They are adhesive.
C) Water has a high specific heat. D) Water has a high heat of vaporization.
E) Water’s greatest density is at 4°C. Above or below that temperature it becomes less dense.
F) Water has a low viscosity. Read the following scenario and determine which of the previous properties is BEST illustrated. As raindrops fall on a solid surface, they quickly tend to form beads or drops. what is the correct answer a,b,c,d,e,f?
Explanation / Answer
The correct answer is (a) that is cohesion. The water molecuules due to cohesion tend to attract the surrounding molecules and this creates surface tension. Thus in order to have the lowest energy state water molecules takes the shape of a sphere since sphere have the minimum surface area.
