NEET Physics Bulk Modulus MCQ Question
Type: MCQ-numerical-Medium-Class 11
What is the bulk modulus of water if the initial volume is 100.0 liters and the final volume is 100.5 liters when subjected to a pressure increase of 100.0 atm (1 atm = 1.013 × 10^5 Pa)?
A
02 × 10^9 Pa
B
5.07 × 10^9 Pa
C
01 × 10^8 Pa
D
04 × 10^8 Pa
Correct Answer
Option A
Detailed Explanation
Bulk modulus (K) is computed using K = -ΔP / (ΔV/V₀). With ΔP = 100.0 atm × 1.013 × 10^5 Pa/atm, ΔV = 0.5 liters, and V₀ = 100.0 liters, the calculation yields approximately 2.02 × 10^9 Pa.
