Acertain metal has a coefficient of linear expansion of 2.00 × 10-5 k-1. it has been kept in a laboratory oven at 325°c for a long time. it is now removed from the oven and placed in a freezer at ‐145°c. after it has reached freezer temperature, the percent change in its density during this process is closest to a) +2.90%. b) ‐2.90%. c) +2.74%. d) ‐2.74%. e) it is not possible to tell without knowing the mass and original volume of the metal.
