A certain 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.
