The linear expansivity of brass is 2 x 10-5oC-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
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
