Thermal expansion is the tendency of matter to change in shape, volume, and area in response to a change in temperature. Temperature is a monotonic function of the average molecular kinetic energy of a substance.


A rod having α = 1*10<sup>-5</sup>per °C and length of 70cm has one of its end rigidly connected to another rod of length 1m and α= 0.5*10<sup>-5</sup>per °C. Find the new length of the two joined rods when their temperature is increased by 30℃.
