Solve.A metal rod changes in length by 0.82 mm for every 1°C change in temperature. If it expands when heated and contracts when cooled, express its change in length as a signed number as the temperature changes from 34°C to 25°C.

Fill in the blank(s) with the appropriate word(s).


-7.38 mm

(25 - 34) × 0.82 = (-9) × 0.82 = -7.38
