Question

Match the items in List 1 (names of quantities) with those in List 2 (units of quantities in the SI system). Use codes in List for matching.

List 1	List 2
M. Dynamic viscosity	1. N/m
N. Kinematic viscosity	2. N.m
O. Surface tension	3. N.s/m2
P. Energy	4. m2/s

1. M - 4, N - 3, O - 1, P - 2
2. M - 3, N - 4, O - 1, P - 2
3. M - 2, N - 4, O - 1, P - 3
4. M - 3, N - 4, O - 2, P - 1

Answer 1

Correct Answer - Option 2 : M - 3, N - 4, O - 1, P - 2

Concepts:

Dynamic Viscosity: The property that represents the internal resistance of a fluid to motion (i.e. fluidity ) is called as dynamic viscosity. The dynamic viscosity has the dimension ML^-1 T^-1 and the unit of kg/m.s (or, N.s/m² or Pa.s).  A common unit of dynamic viscosity is poise which is equivalent to 0.1 Pa.s.

Kinematic Viscosity: The ratio of dynamic viscosity to density is called kinematic viscosity. It has got the dimension of LT^-1 and unit of stoke (1 stoke = 0.0001 m²/s).

Surface Tension: Surface tension is the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area. The SI unit is N/m and CGS unit is dyne/cm.

Energy: The energy is defined as the capacity for doing work. It can occur in kinetic, potential, electrical, chemical, nuclear, thermal, and various other forms. It has unit 1 N.m or 1 Joule.
