PROPERTIES OF WATER

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Water sticks to water
A
cohesion
B
adhesion
C
surface tension
D
high specific heat
Explanation: 

Detailed explanation-1: -Water has an amazing ability to adhere (stick) to itself and to other substances. The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a “sticky” liquid.

Detailed explanation-2: -Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.

Detailed explanation-3: -Water molecules are bent so the hydrogen atoms are to one side of the oxygen atom. and when it come to molecules opposites attract. A bond forms between the negative side of one water molecule and the positive side of another. At that is what gives water its stickiness.

Detailed explanation-4: -Water molecules tend to stick together due to the structure and charge of the atoms present in the water. Hydrogen atoms are positively charged while oxygen atoms are negatively charged.

Detailed explanation-5: -Water molecules have an uneven sharing of electrons due to covalent bonding. This creates a negative and positive end of each water molecule. This results in water being attracted to other molecules. This is different from cohesion because cohesion involves the attraction of the same substance or molecule.
