Asas Black
Diketahui :
Q Lepas =
Massa = 100 Gram
massa jenis = 1 kal/ gram°C
suhu = 90°C
Q Terima =
Massa = 200 gram
Massa jenis = 1 kal/ gram°C
Suhu = 30°C
Rumusannya =
Q = Q. lepas = Q Terima
m. c ( T2 - Ta) = m. c. ( Ta - T1)
100 . 1 ( 90 - Ta) = 200. 1 ( Ta - 30)
100 x ( 90 - Ta) = 200 x ( Ta - 30)
9000 - 100Ta = 200 Ta - 6000
9000 + 6000 = 200 Ta + 100 Ta
15.000 = 300 Ta
Ta = 15.000 ÷ 300
Ta = 50 ° Celcius
