When the temperature of a coin is raised by 86.9 C°, the coin's diameter increases by 2.78 x 10-5 m. If the original diameter is 1.73 x 10-2 m, find the coefficient of linear expansion.
(a) of the diameter of a copper sphere is 2.540 cm at 20.00'C, what will its diameter be at a temperature of 108.0"C? The coefficient of linear expansion of copper is 17 x 10-rc. (Give your answer to at least three decimal places) 2.540 X Consider linear expansion along the radial directionem (6) For the volume of the sphere to increase by 1.120, to what temperature should the sphere be heated The content of volume expansion is 3 times that...
A spherical steel ball bearing has a diameter of 2.540 cm at 26.00°C. (Assume the coefficient of linear expansion for steel is 11 ✕ 10−6 (°C)−1. ) (a) What is its diameter when its temperature is raised to 96.0°C? (Give your answer to at least four significant figures.)
A 2.0 kg bar of copper is heated at atmospheric pressure so that its temperature increases from 20°C to 50°C. (a) What is the work done on the copper bar by the surrounding atmosphere? SOLUTION Conceptualize This example involves a solid, whereas the preceding two examples involved liquids and gases. For a solid, the change in volume due to thermal expansion is very small. Categorize Because the expanslon takes place at constant atmospheric pressure, we categorize the process as isobaric...
