Question

The volume of a material reduces by 2% when the pressure is increased from 1 atm to 2 atm. What is its bulk modulus?

• A. \( 10^5 \, \text{N/m}^2 \)
• B. \( 5 \times 10^5 \, \text{N/m}^2 \)
• C. \( 10^6 \, \text{N/m}^2 \)
• D. \( 5 \times 10^6 \, \text{N/m}^2 \)

Hint:

Bulk modulus is always positive. Use \( B = \frac{\Delta P}{|\Delta V/V|} \). Remember: \( 1 \, \text{atm} = 1.013 \times 10^5 \, \text{N/m}^2 \approx 10^5 \, \text{N/m}^2 \) for quick calculations.
