EXPLANATION Soil Solid Phase
  • Soil Volumetric Ratios:
  • Liquid Ratio ($\vartheta$): Defined in soil physics and structural mechanics as the volume of liquid (water) per unit volume of solid matrix:
$$\vartheta = \frac{V_w}{V_s}$$
  • Void ratio ($e$) is $\frac{V_f}{V_s}$, and mass wetness ($w$) is $\frac{M_w}{M_s}$. (Correct answer: Option 4)
