Consider the following statements relating to some fluid properties :

1. The variation of kinematic viscosity between liquids and gases is much less than the variation of dynamic viscosity.
2. Surface energy is caused by relative forces of cohesion and adhesion between the fluids.
3. Mercury possesses larger vapour pressure than benzene and hence benzene is more volatile.
4. Bulk modulus of water is 3,00,000 units and that of gas is 15 units. This indicates that gas is 20,000 times more compressible than water.

Of these statement
