A rod is measured to be exactly 21.81 cm long using a steel ruler at a temperature of 21.5°C. Both the rod and the ruler are placed in an oven with a temperature of 345.0 °C where the rod now measures 21.93 cm using the same ruler. What is the coefficient of thermal expansion for the material of which the rod is made?
I have spent over 8 hours trying to figure this out and cant. I need help mainly figureing out delta L of the rod. Any help would be greatful
