Physics Laboratory Report Linear Expansion Experiment Lab D: Linear Expansion Coefficient Beatriz Cabral Group: 4 Date of Experiment: 10/01/2018 Date of Submission: 10/08/2018 PHYS 103A Lab Instructor’s Name: Haizheng Zhang Partners: Mike Pateiro, Vincent, and Muhammad Khan 1. INTRODUCTION In this lab, my group and I had to understand how to measure the coefficient of linear expression for different metal rods. The metal rods used were Aluminum and Copper. We added heat to the experiment because it is said that it increases the vibrational kinetic energy of the atoms in the material. This also increases the distance between the atoms. The coefficient that we observed depends on many factors, such as the composition and purity of the material and temperature. Our group was able to measure such numbers by using a dial gauge, steam generator, thermometer, and a meter stick. 2. EXPERIMENTAL PROCEDURE Part I: I. Measure the initial length of both rods to the nearest cm (convert it); also take note of the material of the rod II.
