• A. The value of angle of contact for pure water and glass is zero
• B. Angle of contact increases with increase in temperature of liquid
• C. If the angle of contact of a liquid and a solid surface is less than $90^o$ , then the liquid spreads on the surface of solid
• D. Angle of contact depends upon the inclination of the solid surface to the liquid surface
