It is easier to spray water to which soap is added because addition of soap to water

It is easier to spray water to which soap is added because addition of soap to water
  1. decreases surface tension of water
  2. increases surface tension of water.
  3. makes surface tension of water zero.
  4. increases its density.

Solution

- 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 surface tension - In order for water to spray more easily into spaces, the surface tension of water should be decreased, Soap decreases the surface tension of water
