Jawaban:
14,64 cm³
Penjelasan:
Dik :
V awal = 1000 cm³
t awal = 20⁰C
t akhir = 100⁰C
λ gelas = 9.10⁻⁶/⁰C
γ air = 2,1 . 10⁻⁴/⁰C
Dit : Vol air yg tumpah
Jwb:
γ gelas = 3 x 9.10⁻⁶/⁰C = 27 . 10⁻⁶ = 2,7 . 10⁻⁵/⁰C
Δt = 100⁰C - 20⁰C = 80⁰C
Vgelas(100⁰C) = V₀ (1+γΔt)
= 1000 ( 1 + 2,7 . 10⁻⁵.80)
= 1000 + 216 . 10⁻²
= 1000 + 2,16
= 1002,16 cm³
Vair(100⁰C) = V₀ (1+γΔt)
= 1000 ( 1 + 2,1 . 10⁻⁴. 80)
= 1000 + 168.10⁻¹
= 1000 + 16,8
= 1016,8 cm³
Vair yg tumpah = 1016,8 cm³- 1002,16 cm³ = 14,64 cm³
