Lab D: Linear Expansion Coefficient Physics 103A Name: AG & MK Date : 2/23/15 Professor : Farbod Nabar Introduction: The objective of this lab is to measure the coefficient of linear expansion for 3 different metal rods. Linear dimensions for most substances increase when the temp increases in a range that doesn’t produce phase change. The added heat causes an increase in vibrational kinetic energy. The increase in linear dimension is proportional to the increase in temperature and the initial linear dimension. Experimental Procedure: Step 1: Measure the initial length of the rod Step 2: Insert the rod into the heating jacket, pointed against the adjustable screw and flat end against the dial gauge. Step 3: Record the initial temperature. Step 4: Record the initial dial gauge reading. Step 5: Turn on the steam generator and let the steam into the heating jacket until the rod has a steady temperature. Record the steady temperature as the final temperature.
