Class 11 NEET Physics Properties of Matter Questions

Concept:Matching each mechanical property from List I with its correct definition formula in List II.Formula:Young's Modulus: $Y = \frac{\text{Stress}}{\text{Strain}} = \frac{F L}{A \Delta L}$Compressibility: $k = \frac{1}{\text{Bulk Modulus}} = -\frac{1}{\Delta P} \frac{\Delta V}{V}$Bulk Modulus: $B = -\frac{\Delta P}{\Delta V/V} = -P \frac{V}{\Delta V}$Poisson's Ratio: $\mu = \frac{\text{Lateral Strain}}{\text{Longitudinal Strain}} = \frac{\Delta d}{\Delta L} \cdot \frac{L}{d}$Solution:Match each property in List I with its expression in List II using the standard formulas.A. Young's Modulus → Expression II ($\frac{F L}{A \Delta L}$)B. Compressibility → Expression III ($-\frac{1}{\Delta P} \frac{\Delta V}{V}$)C. Bulk Modulus → Expression IV ($-P \frac{V}{\Delta V}$)D. Poisson's Ratio → Expression I ($\frac{\Delta d}{\Delta L} \frac{L}{d}$)Thus the correct mapping is A-II, B-III, C-IV, D-I.Answer:Option D (A-II, B-III, C-IV, D-I)
