Answer: The surface tension of water decreases when the alcohol is dissolved in water.
Explanation:
Surface tension is the tendency of the liquid surface to minimize the surface area. Surface tension is the force per unit length.
When the alcohol is added in water then it will completely dissolved in all proportion as they are miscible.
The surface tension of water is greater than the alcohol due to the greater degree of hydrogen bonding in water. So, by increasing the amount of alcohol in water, the surface tension decreases.
When a sparingly soluble substance like alcohol is dissolved in water, surface tension of water is decrease.
