200. 1. (80 - ts) = 30 . 1 ( ts - 20)
16000 - 200 ts = 30 ts - 6000
ts = 64°C
m= 30 gr= 0,03 kg
m. c. delta t = m. c. delta t
0,02 kg. 4200 J/kg·C. ( tc - 80) = 0,03 kg. 4200 J/kg·C. (20 - tc)
84 (tc - 80) = 126 (20 - tc)
84 tc - 6720 = 2520 - 126 tc
84 tc + 126 tc = 2520 + 6720
210 tc= 9240
tc= 9240/210
tc= 44
semoga membantu :)
