Of these four liquids which is the most viscous? a) h20 b) ccl4 c) c2h12o6 d) hg

Answer is: d) Hg.
Mercury is a chemical element with the symbol Hg and atomic number 80.  Mercury is the only metallic element that is liquid at standard conditions for temperature and pressure.
Absolute viscosity of mercury is 0,0015 Pa·s.
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress

The net force is 100
