bantuuuuuu deadline hari iniii
diketahui :
Q = 4.500 J
m = 10 kg
kalor jenis = 450 J/kg°C
T1 = 20°C
ditanya :
suhu akhir?
Jawab :
Q = m . c . ΔT
4500 = 10 × 450 × ΔT
4500 = 4500 × ΔT
ΔT = 1°C
ΔT = T2 - T1
1 = T2 - 20
T2 = 21°C Jawaban D.
18. 8 kg = 8000 gr
C = m × c
C = 8000 × 2
C = 16000 kal/°C
Jawaban:
itu jawabannya
that's the answer
Penjelasan:
maaf kalo salah
sorry if wrong
