Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Surface tension is the property of water in which ____
A
water molecules at the surface tend to stick together.
B
water spills easily.
C
water tends to be see-through.
D
None of the above
Explanation: 

Detailed explanation-1: -The high surface tension helps the paper clip-with much higher density-float on the water. The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.

Detailed explanation-2: -The surface tension of water is about 72 mN/m at room temperature which is one of the highest surface tension for liquid. There is only one liquid having higher surface tension and that’s mercury which is a liquid metal with a surface tension of almost 500 mN/m.

Detailed explanation-3: -Water is highly cohesive-it is the highest of the non-metallic liquids. Water is sticky and clumps together into drops because of its cohesive properties, but chemistry and electricity are involved at a more detailed level to make this possible.

Detailed explanation-4: -Cohesive forces are responsible for surface tension, a phenomenon that results in the tendency of a liquid’s surface to resist rupture when placed under tension or stress.

Detailed explanation-5: -Cohesion and adhesion are two water properties that describe how water molecules interact with each other. and how water molecules interact with other things like leaves or even you. Cohesion means that water likes to stick to itself. and adhesion means that water likes to stick to other things.
