When the temperature of a metal cylinder is raised from 0.0°C to 95.7°C, its length increases by 0.22%. (a) Find the percent change in density. (b) What is the metal? Use Table below. Some Coefficients of Linear Expansion" Substance a (10-/C°) Ice (at 0°C) Lead 51 29 Aluminum 23 Brass 19 Сopper Concrete Steel Glass (ordinary) Glass (Pyrex) 17 12 11 9 3.2 Diamond Invar 1.2 0.7 0.5 Fused quartz "Room temperature values except for the listing for ice. This alloy was designed to have a low coeffi- cient of expansion. The word is a shortened form of "invariable." (a) Number i Units (b)
