1.	Whena metal rod is cooled from 500^(0)Cto 0^(0)C, its density increases by1.027times. Determine the coefficient of linear expansion of this metal.
Answer» SOLUTION :`t_(2)=500^(@)C, t_(1)=0^(0)C, d_(0)=1.027 d_(t)` `gamma =(d_(0)-d_(t))/(d_(t)(t_(2)-t_(1)))=((1.027-1))/((500)) = (0.027)/(500), alpha=(gamma)/(3)=(0.027)/(3xx500) = 0.000018//""^(0)C`.
