The coefficient of thermal expansion of water at 20ºC is 0.207 x 10^-3 K^-1 A thin glass tube contains a 75.0 cm column of water at 20ºC. If the thermal expansion of the glass tube is negligible, by how much does the length of the column of water expand when it is heated to 80ºC? A) 3.1 mm B) 9.3 mm C) 12.4 mm D) 4.1 mm E) 28 mm

Question

Quizplus · Accepted Answer

The change in length can be calculated using the formula for linear expansion: ΔL = L₀ * α * ΔT, where L₀ is the initial length, α is the coefficient of thermal expansion, and ΔT is the change in temperature. Substituting the given values: ΔL = 75.0 cm * 0.207 x 10^-3 K^-1 * (80ºC - 20ºC) = 9.3 mm.
