The property of surface tension tends to persists even if a liquid is solidified. Hence, solids can also be assumed to possess surface tension. Consider a liquid in contact with a solid with air above. Let T_1 , T_2 and T_3 be the surface tension at the liquid-air interface, solid-air interface and the solid-liquid interface. The liquid drop will spreads on the solid surface if

1.	The property of surface tension tends to persists even if a liquid is solidified. Hence, solids can also be assumed to possess surface tension. Consider a liquid in contact with a solid with air above. Let T_1 , T_2 and T_3 be the surface tension at the liquid-air interface, solid-air interface and the solid-liquid interface.
