Sepotong besi panjangnya 1 meter dipanaskan dari suhu 25°C menjadi 125°C. Jika koefisien pemuaian linier besi 11.10pankat-6/°C, maka panjang besi tersebut adalah...
Zuhh
Dik : L0 = 1 m T0 = 25 C T = 125 C α = 11x10⁻⁶/C dit: L ?
dijawb : L = L0 (1+α x ΔT) = 1 (1 + 11x10⁻⁶ x (125-25)) = 1 (1 + 11x10⁻⁶ x 100) = 1 (1 + 11x10⁻⁴) = 1,0011 m
L0 = 1 m
T0 = 25 C
T = 125 C
α = 11x10⁻⁶/C
dit: L ?
dijawb :
L = L0 (1+α x ΔT)
= 1 (1 + 11x10⁻⁶ x (125-25))
= 1 (1 + 11x10⁻⁶ x 100)
= 1 (1 + 11x10⁻⁴)
= 1,0011 m
