Question

Calorimetry means measurement of heat. When a body at higher temperature is brought in contact with a body at lower temperature, the heat lost by the former is equal to the heat gained by the latter (no heat should escape to the surroundings)

explain in hindi?

Solution

Calorimetry एक विज्ञान है जिसके माध्यम से उष्मा ऊर्जा (heat energy) को मापा जाता है। एक वस्तु जो पहले से ही उच्च तापमान (higher temperature) पर है यदि उसे निम्न तापमान (low temperature) वाली वस्तु के साथ रखा जाता है, तो पहली वस्तु द्वारा उत्सर्जित (emitted) ऊर्जा दूसरी वस्तु द्वारा उतनी ही मात्रा में अवशोषित (absorbed) कर ली जाती है। (ऊष्मा ऊर्जा वातावरण में release नहीं होती है।)

Hum ye jante hai k heat energy higher temperature se low temperature ki taraf flow karti hai isliye jab hum 1 higher temperature body ko low temperature body k sath rakhte hai to heat flow karti hai from higher temperature to low temperature taki system equilibrium me rahe. Jitni heat energy higher body loose karta hai utni he heat energy low temperature body gain karta hai without loosing it to surrounding.
