part 1 of 3 A 150 kg steel rod in a building under con- struction supports a load of 6240 kg. During the day the rod's temperature increases from 23C to 41C, causing the rod to thermally expand and raise the load 5.0 mm. Find the energy transferred as heat to or from the rod. (Assume the specific heat ca- pacity of steel is the same as for iron.) The acceleration of gravity is 9.81 m/s. The spe- cific heat of iron is 448 J/kg. C. Answer in units of J. part 2 of 3 part 3 of 3 Find the work done by or on the rod in this process. Answer in units of J. How great is the change in the rod's internal energy?
