My physics laboratory was about thermal expansion of metals. Aluminium and copper tubes were the metals that I used for the experiment. In this lab I observed how different metals expand in different temperatures. To find the coefficient of expansion I had to place a long rod of copper in an enclosed tube. I then heated the tube using steam from boiling water. I observed the change in temperature and measured the change in length. What are some sources of...
