A copper at 100 °C placed in 1250-gram of water at 10 °C. The specific heat for water is 4200 J.kg 'C' and the specific heat for copper is 389 J.KG 'C. If the temperature of the thermal equilibrium 36 °C, what is the mass of copper
![]()
Jawaban:
1250 gr = 1,25 kg
Q = m . c . ∆T
m = mass
c= specific heat capacity
∆T = temperature change
mass . 389 . (100-36) = 1,25 . 4200 ( 36-10)
mass. 389 . 64 = 1,25 . 4200 . 26
mass = 4,38624..... kg
mass = 4,4 kg
sry if i'm wrong, cuz my english ain't that good enough.
