Water evaporates under atmosphere pressure without changing the temperature the same water is placed in particle vacuum the rate it evaporates will.
Surface tension is the elastic tendency of a fluid
surface which makes it acquire the least surface area possible.The cohesive
forces between liquid molecules are responsible for the phenomenon.
Some notable applications of surface tension are:
● A needle placed on water can be made to float due to
the surface tension of water.
● Warm water is used for washing purpose as heating
increases the surface area and reduces surface tension.
● Mosquito eggs can float on water because of its surface
tension.
● Toothpaste contains soap, which reduces the surface
tension and helps it spread freely in the mouth.
● Surface tension prevents water from passing through the
pores of an umbrella.
● Antiseptics like Dettol have low surface tension, so
that they spread faster.
