What condition must be met for adhesion to occur between a solid and a liquid?

Show Answers

The liquid must spread over the solid surfaceThere should be mechanical interlocking between themThe contact angle must be largeNone of these options apply

Explanation

For adhesion to take place between a solid and a liquid, the liquid needs to wet the solid surface, meaning it must spread out rather than form droplets. Mechanical interlocking and a high contact angle do not ensure adhesion in this context.
