विशिष्ट ऊष्मा क्षमता:
- इसे इसके तापमान में एक डिग्री परिवर्तन करने के लिए आवश्यक ऊष्मा की मात्रा के रूप में परिभाषित किया जा सकता है।
- गणितीय रूप से, आवश्यक ऊष्मा, Q = mcΔT,
- जहाँ, m = द्रव्यमान, c = विशिष्ट ऊष्मा क्षमता, ΔT = तापमान अंतर
- इसे Jg-1K-1 में मापा जा सकता है।
गणना:
दिया गया है: द्रव्यमान, m = 500 g, तापमान अंतर, ΔT = 80ºC, ऊष्मा, Q = 10 kJ
विशिष्ट ऊष्मा क्षमता,
इसलिए, विशिष्ट ऊष्मा क्षमता 0.25 Jg-1K-1 है।
