Practice question

Bulk modulus: B = −pΔVV. Rearrange: ΔVV = −pB = −2×1062.2×109≈−9.09×10−4. Magnitude: 9.09×10−4. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 9.09×10−4. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
