The linear expansivity of brass is 2 x 10-5 oC-1. If the volume of a piece of brass is 10cm3 at 0oC, what will be its volume at 100oC?
A
10.02cm3
B
10.04cm3
C
10.06cm3
D
10.20cm3
E
102.00cm3
Verified Correct Answer: C.
Physical Principles & Numerical Solution
3 x \(\alpha\) = \(\frac{V_2 - V_1}{\Delta \theta \times V_1}\)
3 x 2 x 10-5 = \(\frac{V_2 - 10}{10 \times 100}\)
V2 = 10.06cm3
