आयतन प्रसार गुणांक:
- यह परिवेश के दाब के नियत होने के साथ तापमान में प्रति इकाई परिवर्तन के आकार के आंशिक परिवर्तन का माप है।
- यह विशेष पिंड के आयतन को प्रभावित करता है।
- यह गुणांक द्रव पदार्थों पर सबसे अधिक लागू होता है।
- यह आम तौर पर तापमान पर निर्भर करता है क्योंकि तापमान में बाद में वृद्धि के साथ गुणांक बढ़ता है।
- एक छोटे से तापमान परिवर्तन के लिए, ∆T, आयतन में आंशिक परिवर्तन, ∆V/V, ∆T के सीधे समानुपाती है।
- ∆V/V = αv ∆T, जहाँ αv आयतन विस्तार का गुणांक है।
