Textile Engineering > GATE 2024 > Interfacial Forces
Consider the following diagram where an oil droplet is formed on a fabric immersed in water. At equilibrium, the balance of various interfacial forces acting on the droplet is given by the following equation
γFW = γFO + γOWcosθ
When a surfactant is added to water, assuming that γOW and γFO remain unchanged, the following happens _______.
A
γFW decreases and the oil droplet tends to become rounder
B
γFW decreases and the oil droplet tends to become flatter
C
γFW increases and the oil droplet tends to become rounder
D
γFW increases and the oil droplet tends to become flatter

Correct : a
