A particular device needs to be made that will experience a change in temperature of 100 °C. Two materials are being considered: copper (α = 1.7*10-5 °C-1) and steel (α = 1.3*10-5 °C-1). If made of copper, the device would be 2 m in length. If made of steel, the device would be 2.615 m in length. Which device would experience more thermal expansion?
