Question

Benda X mengalami kenaikan suhu dari 27°C menjadi 35°C. Jika volume awal benda 5 cm³, volume akhir benda....cm³. ( a = 5 × 10-6/°C)

Answer 1

Diketahui
α = 5 x 10⁻⁶ /°C
ΔT = ( T₂ - T₁ )
ΔT = ( 35 - 27 )
ΔT = 8 °C

Vo =  5 cm³ [ ndak usah dirubah ]

Jawab

Vt = Vo ( 1 + [ 3α. ΔT )
Vt = 5 ( 1 + [( 3 x 5 . 10⁻⁶ ) 8 ]
Vt = 5 ( 1 + [( 1,2 x 10⁻⁴ )]
Vt = 5 ( 1,00012 )
Vt = 5,0006 cm³
