Answer: Option (b) is the correct answer.
Explanation:
Porosity means the ease with which a fluid can pass through between a rock or cracks etc.
If particles of a soil are flat and even if they are sorted then there will rarely be any space available for fluid or water to pass through it.
If soil particles are round in shape and are sorted then there will be space available for the fluid to pass through it. Hence, this type of soil will be most porous.
Similarly, if soil particles are round but are unsorted then there will be less space available as compared to sorted particles. This is because particles are placed randomly so, somewhere there will be much less space and somewhere there will be large space available. As a result, soil will not be most porous.
If soil particles are flat and unsorted then there will also be less space available for the fluid to pass through it. Thus, soil will be less porous.
Hence, we can conclude that out of the given options, soil B - round, sorted particles is the most porous.
D
Boiling and melting are both physical changes so do not involve the formation or breakage of chemical bonds.
