yang bisa jawab aku kasih jawaban terbaik deh.....
yang jawabnya asal asalan aku laporin, please buat sekarang
makasih

No 23. diket m=0,2 kg...C=4200....delta T = 80 (100-20) ditanya Q Jwab. Q = m.C.delta T = 0,2 x 4200 x 80 = 67200

21. Jawab : (Y) = 3 x α =0,0000765/°C V₀ = 9³ = 729cm³ ΔV = Vo x Y x Δt = 729cm³ x 0,0000765/°C x (100°C-25°C) = 4,18264 m (C)
23. Jawab : Q = m x c x ΔT Q = 200 gram x 1 kal/g°C x 80°C Q = 16000 kal Q = 16 kkal (B)
25. Jawab : W = p x t =450 W x 900 s = 405.000 J Q = m x c x Δ t ---> W = Q1, maka 405000 joule = m x 4200 J/kg°C x 80°C m = 405.000 / 336.000 kg m =1,205 kg (C)
26. Jawab : P1 x V1 = P2 x V2 250 x 1 = 50 x P2 P2 = 250 / 50 P2 = 5 atm (D)
27. Jawab : R = (4/5) C R = (4/5) 77°C R = 61,6° R (C)
diket m=0,2 kg...C=4200....delta T = 80 (100-20)
ditanya Q
Jwab. Q = m.C.delta T
= 0,2 x 4200 x 80
= 67200
(Y) = 3 x α
=0,0000765/°C
V₀ = 9³ = 729cm³
ΔV = Vo x Y x Δt
= 729cm³ x 0,0000765/°C x (100°C-25°C)
= 4,18264 m (C)
23. Jawab :
Q = m x c x ΔT
Q = 200 gram x 1 kal/g°C x 80°C
Q = 16000 kal
Q = 16 kkal (B)
25. Jawab :
W = p x t
=450 W x 900 s
= 405.000 J
Q = m x c x Δ t
---> W = Q1, maka
405000 joule = m x 4200 J/kg°C x 80°C
m = 405.000 / 336.000 kg
m =1,205 kg (C)
26. Jawab :
P1 x V1 = P2 x V2
250 x 1 = 50 x P2
P2 = 250 / 50
P2 = 5 atm (D)
27. Jawab :
R = (4/5) C
R = (4/5) 77°C
R = 61,6° R (C)
Moga membantu.
