विशिष्ट ऊष्मा क्षमता:
- त्याची व्याख्या एका अंशाने तापमान बदलण्यासाठी आवश्यक उष्णतेचे प्रमाण अशी केली जाऊ शकते.
- गणितीयदृष्ट्या, आवश्यक उष्णता, Q = mcΔT,
- जिथे m = वस्तुमान, c = विशिष्ट ऊष्मा क्षमता, ΔT = तापमानातील फरक
- उष्णता ज्युल (J) मध्ये मोजली जाऊ शकते.
गणना:
दिलेले आहे: वस्तुमान, m = 100 g = 0.1 kg, तापमानातील फरक, ΔT = 40ºC, चांदीचा विशिष्ट ऊष्मा क्षमता, c = 236 J/ kg K
आवश्यक उष्णता, Q = mcΔT
Q = 0.1 x 236 x 40
Q = 944 J
म्हणून, दिलेले विशिष्ट तापमान वाढवण्यासाठी आवश्यक ऊर्जा 944 J आहे.
