When a metal ball is heated through 30oC,its volume becomes 1.0018cm3. If the linear expansivity of the material of the ball is 2.0 x 10-5 K-1, calculate its original volume
-
A.
1.0000cm3 -
B.
1.0020cm3 -
C.
1.0036cm3 -
D.
1.0180cm3
Correct Answer: Option A
Explanation
(V_1 = frac{V_2}{3} = frac{1.0018}{3 times 2.0 times 10^{-5} times 30 + 1})
= 1cm3
