OBJECTIVES●To measure the coefficient of linear expansion for different metal rods.2. THEORETICAL BACKGROUND●Linear dimensions for most substances increase as the temperature increases in a range that does not produce a change of phase. The added heat increases the vibrational kinetic energy of the atoms in the material, which in turn increases the distance between the atoms. To a first approximation, the increase in a linear dimension is proportional to the increase in temperature and the initial linear dimension.
3. PROCEDURE1.Measure the initial length of the experimental rod to the nearest and the material of the rod. 2.Carefully insert the rod into the heating jacket so that its pointed end is
