1.The force behind the existing of surface tansion is ?
- Comprehensive
- cohesion
- Adhesion
- Tension
Ans(2): Surface Tension is a tensile force acting on the surface of a liquid in contact with gas or on the surface between two immiscible liquid.
It is a surface phenomenon.
It is due to cohesion only
2.The SI unite 1 cubic metre per second is equal to
- 1000 litre per second
- 10 liter per second
- 1 litre per second
- 100 litre per second
Ans.(1) ; 1 m³ =1000 litres,
: 1M³ per second=1000 Litre per second
3.The force behind the existing of surface tansion is:
- P
- roh
- rohT
- P/roh
4.Fluids under go volumetric change under the action of external force due to
- bulk modulus
- compressibility
- incompressibility
- capillarity
Fluids undergo volumetric change under the action of force due to compressibility
- it is inverse of bulk modulus elasticity.
- it is denoted by beta
