Mercury does not wet glass - the cohesive forces within the drops are stronger than the adhesive forces between the drops and glass. When liquid mercury is confined in a tube, its surface (meniscus) has a convex shape because the cohesive forces in liquid mercury tend to draw it into a drop.
13) Mercury does not wet glass. This is due to property of liquid known as

Answer is:
9.81 x 103 N/m3
Explanation:
Weight density or specific weight is defined as the weight per unit volume of a liquid at a standard temperature and pressure. Weight density or specific weight is usually denoted by w. Weight density or specific weight is expressed in kN/m3 or N/m3 or N/mm3.
Mathematically, weight density or specific weight,
w = ρ.g
Note: For water, w = 9.81 kN/m3 = 9.81 x 103 N/m3 = 9.81 x 10-6N/mm3.
