A thin metal rod that is $34\mathrm{.}00$cmcm long at $20$C$$C expands in length by $3\mathrm{.}70$mmmm when its temperature is increased to $493$C$$C$.$ What would happen to the rod if it was instead cooled to $-250$C$$C$?$

The rod would expand by$1\mathrm{.}96$mmmm$.$The rod would contract by$1\mathrm{.}96$mmmm$.$The rod would contract by $2\mathrm{.}11$ mmmm$.$The rod would expand by $2\mathrm{.}11$mmmm$.$
