Question

Tolong jawab semu a nomor ya aku bingung soalnya ini bwat besok

Answer 1

1. dik = m = 2 kg
c = 460 j / kg°c
T.= 15°c
T= 100°c
∆T = T - T.
= 100°c - 15°c = 85°c
dit = Q =.........?
jwb= Q= m . c . ∆T
= 2 kg . 460 j / kg°c . 85°c
= 78200 j
2.dik = m = 10 kg
c = 4200 j / kg °c
T = 100°c
T. =25°c
∆T = T-T.
= 100-25 = 75
dit = Q=.........?
jwb = Q = m . c . ∆T
= 10 kg . 4200 j / kg ° c . 75°c
= 3 150 000
#bisanya hanya segitu
