A rod with a length of 1.5 m is made of steel, which has a coefficient of linear expansion of 1.10 ✕ 10−5 (°C)−1. It is initially at a temperature of 28°C.   (a) What is the change in length of the rod if the temperature drops to 0.0°C? (Give the absolute value in units of mm.) ___ mm   (b) How does the rod's length change with lower temperature? - The rod shrinks with lower temperature. - The rod expands with lower temperature.  - The rod's length does not change with lower temperature.   (c) Find the absolute value of the fraction by which the rod's length changes between the two temperatures. |ΔL/L0| = ___
