A.) The linear coefficient of thermal expansion for concrete is 12x10^-6 ºC^-1. Consider a slab of concrete which is 4.0 m long at 0.0 ºC. What is the change in length if the temperature is increased to 77 ºF? (Note that a conversion is necessary here). Show your work.

B.) What seems to be the primary safety concern in the lab?

C.) Why should you pay close attention to the dial gauge when the rod is expanding?
