Answer 2

Answer:

The accurate answer is option is (B) void volume/bulk volume.

Explanation:

The first equation uses the total dimensions and the dimensions of the void. Porosity = (dimensions of Voids / Total dimensions ) $\times 100$%. The second equation uses the total dimensions and the dimensions of the solid. Porosity $=$ ( ( Total dimensions - dimensions of the Solid ) / Total dimensions ). $\times 100$%.It is defined as the ratio of the dimensions of the voids or pore space divided by the total dimensions.

Hence, the correct answer is (B) void volume/bulk volume.
