The temperature coefficient of resistance α in equation R(T)=R0[1+α(T−T0)] equals the temperature coefficient of resistivity α in equation ρ(T)=ρ0[1+α(T−T0)] only if the coefficient of thermal expansion is small. A cylindrical column of mercury is in a vertical glass tube. At 20 ∘C, the length of the mercury column is 12.0 cm. The diameter of the mercury column is 1.6 mm and doesn't change with temperature because glass has a small coefficient of thermal expansion. The coefficient of volume expansion of...
The linear coefficient of thermal expansion for water at 20oC is 69 x 10-6 K -1 . What is the magnitude of the percentage change in density of 1 m3 of water when it is heated from 20oC to 21oC? Density of water = 1000 kgm-3.
In this solution, just trying to understand why the coefficient of thermal expansion of steel is multiplied by 3. I understand volume is cubic. Don't need answer. Thx The average coefficient of volume expansion for carbon tetrachloride is 5.81 ✕ 10−4 (°C)−1. If a 55.0-gal steel container is filled completely with carbon tetrachloride when the temperature is 10.0°C, how much will spill over when the temperature rises to 26.5°C? (Assume the coefficient of thermal expansion of steel is 11 ✕...
