Question

Please bantuin jawab yg nomer 3!

Answer 1

Diketahui :
Vo = 1000 cm3
To = 0 C
Tt = 55 C
ΔV = 8,95 cm³
γraksa = 18x10⁻⁵/C
Ditanyakan : γ gelas ?

Dijawab :
ΔV = Vo x (γarksa - γ air) x (Tt-To)
8,95 = 1000 x (18x10⁻⁵- γ air) x (55-0)
8,95 = 55.000 x (18x10⁻⁵- γ air)
(18x10⁻⁵- γ air) = 8,95/ 55.000
(18x10⁻⁵- γ air) = 0,0001627
γ air                  = 0,0001627 + 0,00018
γ air                  = 0,0003427
γ air                  = 3,427x10⁴/C
