The linear expansivity of brass is 2 x 10
-5 oC
-1. If the volume of a piece of brass is 10cm
3 at 0
oC, what will be its volume at 100
oC?
-
A.
10.02cm3
-
B.
10.04cm3
-
C.
10.06cm3
-
D.
10.20cm3
-
E.
102.00cm3
Correct Answer: Option C
Explanation
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
