What's the length of an aluminum rod at 65 C if its length at 15 C is 1.2 meters? A. 0.001386 meter B. 1.214855 meters C. 1.201386 meters D. 0.00180 meter

The length of an aluminum rod at 65°C if its length at 15°C is 1.2 meters is 1.201386 meters . Change in length = change in temp* length *coefficient of linear expansion of aluminium , coefficient of linear expansion of aluminium = 23 *10^6 degree C^-1 , change in length = 23 *10^6 * 1.2 * ( 65-15) , change in length = 1.2 * 23 *10^(6) * 50 = 0.00138 , Total length = 1.2 + 0.00138 = 1.20138 meter ,
