Answer:
The particles of matter are in constant motion.
Explanation:
Let us consider each statement:
1) Matter consists of only large molecules: No it is not necessary that matter consists of only large molecules, it depends upon the nature of matter.
2) Matter is made up of only charged particles: no the matter may have any kind of particles charged or uncharged.
3) The particles of matter are in constant motion: Yes according to kinetic theory the matter particles are in constant motion.
4)The particles of matter have zero kinetic energy: it is not possible.
The process referred to here is <u>filtration.</u>
The buoyant force is an upward force on an object submerged in a fluid. It is the resultant of the pressure force on the surface of the object. The buoyant force may be larger than the weight of the object causing it to accelerate upwards.
Conclusion:
The weight of the water displaced by the object is subtracted from the actual weigh of the object (out of water), leaving the object with a net positive weight while submerged.
