3:49 PM Ooo AT&T; session masteringphysics.com Problem 12.82 MasteringPhysics Problem 12.82 An aluminum block measures I.050 cm by 2.050 cm by 3.150 cm Find its volume after a 150 C temperature increase in two ways. Part A Find its volume after a 150 C temperature increase using aluminum's linear expansion coefficient on each side and then determining the new volume. Express your answer with the appropriate units. Value Units Submit Give U Part B Find its volume after a 150 C temperature increase using the volume expansion coefficient.

Explanation / Answer

A) Volume = 0.0105*0.0205*0.0315*(1+150*23.1e-6)^3

= 6.851*10^-9 m^3

B) Volume = 0.0105*0.0205*0.0315*(1+150*69e-6)

=   6.851*10^-9 m^3
