A150 cm long copper rod is 3kg in mass. What is the change in length (in centimeters) in the rod if 45000 J of energy is transferred to it? The coefficient of linear expansion of copper is 17x10^-6 /C°. The specific heat capacity of copper is 390 J/kg.C°

Super Invar, an alloy of iron and nickel, is a strong material with a very low coefficient of thermal expansion (0.20 x 10-6 C°). A 1.8-m-long tabletop made of this alloy is used for sensitive laser measurements where extremely high tolerances are required.

a.Plot P vs T graph for the constant V using Excel. Choose the independent variable T along the x-axis and P along the y-axis. Is the graph linear? If so, use a linear fit and write down thebequation of the best-fit straight line. If not, use a power law fit of y = xn. What is the value of n? Based on the fit, are the variables directly or inversely proportional?
