Determine the contact angle between liquid polyethylene (PE) and a solid slab of polystyrene (PS) at 200°C. Assume that the surface tension of the PE is 0.036 N/m, and for the PS it is 0.035 N/m. The interfacial tension between PE and PS is presented in Table 3.3.
What will be an ideal response?
From Table 3.3 the interfacial tension between PE and PS is 0.0044 N/m. Inserting known values into Young’s equation

A little magnetic compass has a needle whose tips are clearly labeled N and S. The compass is placed next to a single circular loop of wire lying flat on a wooden table. The current in the loop is clockwise. What happens?
A. The S tip of the needle is attracted toward the loop B. The needle orients itself with the N tip pointing in the direction of the current in the segment of the loop closest to the needle C. The needle orients itself with the S tip pointing in the direction of the current in the segment of the loop closest to the needle D. The N tip of the needle is attracted toward the loop E. None of these choices are correct
