100 ग्राम द्रव्यमान वाले ताँबे के एक गोले का ताप T है । उसे एक 170 ग्राम पानी से भरे हुए 100 ग्राम के ताँबे के कैलोरीमीटर जोकि कमरे के तापमान पर है, में दाल दिया जाता है । तत्पश्चात निकाय का तापमान `75^(@)C` पाया जाता है । T का मान होगाः (दिया हैः कमरे का ताप `=30^(@)C`, ताँबे की विशिष्ट ऊष्मा = 0.1 कैलोरी/`"ग्राम"^(@)C`)
A. `825^(@)C`
B. `800^(@)C`
C. `885^(@)C`

Best answer
Correct Answer - C
ताँबे के गोले द्वारा दी गई ऊष्मा = कैलोरीमीटर द्वारा ली गई ऊष्मा + जल द्वारा ली गई ऊष्मा
`100 xx 0.1 xx (T -75) = 100 xx 0.1 xx (75-30) + 170 xx 1 xx (75-30)`
`10 (T -75) = 450 + 7650 = 8100`
` T = 810 + 75 = 885^(@)C`
