Question

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

Answer 1

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.
