Use the information below to answer this question.
In an experiment on soil porosity, the following results were obtained:
Volume of dry soil = 52cm³
Volume of water= 48cm³
Volume of soil and water=78cm³
Determine the volume of airspace in the soil sample.
22cm³
26cm³
30cm³
100cm³
Explanation
The expected total volume of soil and water = 52\(cm^3 + 48cm^3= 100cm^3\)
Given total volume of soil and water = 78\(cm^3\)
Difference in total volume = 100\(cm^3 - 78cm^3\) = 22\(cm^3\)
So, this difference represents air space in the soil sample = 22\(cm^3\)
