11. For Newtonian fluids, the shear strain is linearly proportional to the shear stress. 12. For Newtonian fluids, the viscosity is constant with pressure and temperature. 13. The 'thicker' the liquid, the greater viscosity it tends to have 14. To have a large soap bubble, one should blow with high pressure. 15. Mixing soap with water increases the surface tension and hence bubbles tend to form. 16. Dropping liquid mercury on the floor will not 'wet' the floor surface because the intermolecular force between mercury molecules is lower than the attractive force between mercury molecules and the solid surface. 17.
