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
Verified Correct Answer: C.
Physical Principles & Numerical Solution
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
