- आयतन प्रत्यास्थता मापांक: प्रत्यास्थ सीमा में द्रवस्थैतिक प्रतिबल और आयतनी विकृति का अनुपात आयतन प्रत्यास्थता मापांक कहलाता है। इसे K द्वारा दर्शाया जाता है।
\(K=-\frac{dP}{\frac{dV}{V}}\)
- आयतन प्रत्यास्थता की SI इकाई दाब यानि, Nm–2 या Pa के समान होती है।
- संपीड्यता: एक निकाय के सामग्री के आयतन प्रत्यास्थता मापांक का व्युत्क्रम उस सामग्री का संपीड्यता कहलाता है।
\(compressibility ∝ \frac{1}{Bulk \;Modulus}\)
व्याख्या:
- चूंकि संपीड्यता आयतन प्रत्यास्थता मापांक का व्युत्क्रम है संपीड्यता की इकाई ∝ 1/थोक मापांक की इकाई ∝ 1/Nm–2 ∝ m2N-1 ∝ m2/N। तो विकल्प 3 सही है।
