Detailed Solution
Download Solution PDFसंकल्पना:
उष्णता क्षमता:
- हे तापमानातील बदलासाठी पुरवल्या जाणार्या उष्णतेच्या प्रमाणाचे गुणोत्तर आहे तर विशिष्ट उष्णता क्षमता म्हणजे तापमानात बदललेल्या प्रति युनिट वस्तुमानात पुरवलेल्या उष्णतेचे प्रमाण.
- सूत्र, उष्णता क्षमता,\(C=\frac{Q}{Δ T}\) , जेथे Q = उष्णता, ΔT = तापमान फरक
- उष्णता क्षमता JK-1 मध्ये मोजली जाऊ शकते.
गणना:
दिलेल्याप्रमाणे: वस्तुमान, m = 200 g = 0.2 kg, तापमानातील फरक, ΔT = 8ºC, उष्णता, Q = 2000 J
उष्णता क्षमता,\(C=\frac{Q}{Δ T}\)
\(C=\frac{2000}{8}=250 JK^{-1}\)
म्हणून, उष्णता क्षमता 250 JK-1 आहे.
Additional Information
विशिष्ट उष्णता क्षमता:
- त्याचे तापमान एका अंशाने बदलण्यासाठी आवश्यक उष्णतेचे प्रमाण म्हणून त्याची व्याख्या केली जाऊ शकते.
- गणितानुसार, उष्णता आवश्यक आहे, Q = mcΔT,
- जेथे m = वस्तुमान, c = विशिष्ट उष्णता क्षमता, ΔT = तापमानातील फरक
- उष्णता जूल (J) मध्ये मोजली जाऊ शकते.
