Surface Tension
PHXI10:MECHANICAL PROPERTIES OF FLUIDS

361126 Mercury does not wet glass, wood or iron because

1 Cohesive force is less than adhesive force
2 Cohesive force is greater than adhesive froce
3 Angle of contact is less than \(90^{\circ}\)
4 Cohesive force is equal to adhesive force
PHXI10:MECHANICAL PROPERTIES OF FLUIDS

361127 Nature of meniscus for liquid of \(0^{\circ}\) angle of contact

1 Plane
2 Parabolic
3 Hemi-spherical
4 Cylindrical
PHXI10:MECHANICAL PROPERTIES OF FLUIDS

361128 Soap helps in cleaning clothes, because

1 Chemicals of soap change
2 It increases the surface tension of the solution
3 It absorbs the dirt
4 It lowers the surface tension of the solution
PHXI10:MECHANICAL PROPERTIES OF FLUIDS

361129 A liquid does not wet the sides of a solid, if the angle of contact is

1 Zero
2 Obtuse (More than \(90^{\circ}\) )
3 Acute (Less than \(90^{\circ}\) )
4 \(90^{\circ}\)
