The linear expansivity of brass is 2 x 10-5C-1. If the volume of a piece of brass is 15.00cm3 at 00C, What is the volume at 100oC?

A.

16.03cm3

B.

16.00cm3

C.

15.09cm3

D.

15cm3

View answer & explanation

Correct answer is C

linear expansivity = \(\frac {V_2 - V_1}{V_1 {\times} {\Delta}{\theta}}\)

3 x 2 x 10-5 =\(\frac {V_2 - 15}{15 {\times} (100 - 0)}\)

V2 = 15.09cm3
