That's your </span>answer!!
Hope I helped!! :)
Answer : As I understand this is question of matching the correct pairs.
So here are the correct pairs.
1) The attraction
between molecules at the surface of a liquid column
---->Surface tension
Surface tension is a phenomenon observed at the <span>surface film of a liquid which is usually caused by the attraction of the particles on the surface layer by the bulk moiety of the liquid, and which tends to minimize its surface area.</span>
2) The energy of
motion
----> Kinetic energy
Kinetic energy is the energy which is possessed by an object due to motion.
3) The movement
of liquids through the spaces of materials
----> Capillary action
Capillary action is defined as<span> the ability of any liquid to flow through the narrow spaces without any of the assistance, or even in opposition to, external force like gravitational force.</span>
4) The overall
movement of suspended or dissolved particles resulting from the random movements
of individual particles
----> Diffusion
Diffusion in liquids can be defined as the random movement of particles which are dissolved or are in suspended state in liquid.
5) Attraction of
one particle in a material for another
----> Cohesion
Cohesion is defined as the attraction between two different particles in a state of matter
6) The
attraction between unlike substances
----> Adhesion
Adhesion is a property of attraction between two unlike substances.
7) A measure oof
the resistance of a liquid to flow
----> Viscosity
Viscosity is the term used to define as the resistivity of liquid to flow.
As given that some volume of water has been dispensed say "x mL"
The initial weight of bottle =8.4376 g
The final weight of bottle + water =28.5845 g
So weight of water transferred = 28.5845 g - 8.4376 g = 20.1469 g
Now there is a relation between density, mass and volume
density = mass / volume
Therefore
Volume = mass / density
So volume of water dispensed = mass dispensed / density =20.1469 g / 0.9967867 g/ml.
Volume of water = 20.2118467 mL
It is gas such as oxygen,nitrogen,hydrogen,etc
