A. Water has an angle of contact equal to 118° with a certain type of plastic. The surface tension of water (with itself) is 0.07 N/m. What is the adhesive surface tension between water and this plastic? Give your answer in units of N/m. B. When drops of water are placed on a surface made of this type of plastic, do the drops bead up (like on wax), or spread out (like on glass)? a. Bead up b. Spread out c.
