विशिष्ट ऊष्मा धारिता:

  • इसे इसके ताप को एक डिग्री बदलने 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 धारिता, ΔT = तापांतर
  • ऊष्मा को जूल (J) में मापा जा सकता है।

व्याख्या:

आवश्यक ऊष्मा, Q = mcΔT

\(c=\frac{Q}{m\Delta T}\)
