Solution

  • Volume is the amount of space that a substance or object occupies, or that is enclosed within a container.

V=massdensity=kgkgm3

  • Magnitude simply means “how much”. In physics, we use many kinds of numbers, two of which are scalars and vectors. A scalar is a number that only has a magnitude or an amount.
  • Density is a defined as mass per unit volume. density can be calculated with respect to length, area, as well as volume.
density=massvolume=kgm3

  • Diffusion is the net movement of molecules or atoms from a region of high concentration to a region of low concentration as a result of random motion of the molecules or atoms.
  • Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one.
