Which outcome occurs when exceeding mercury's cohesive binding energy?

A)Reduced convective heat transfer
B)Surface tension decreases sharply
C)Wetting angle remains constant
D)Viscosity increases exponentially

💡 Explanation

Reduced binding energy means liquid phase weakening. Boiling occurs when thermal energy exceeds the cohesive forces characterized by surface tension; mercury's surface tension dramatically decreases because the molecules separate, rather than increasing as the substance boils.
