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
Correct Answer: Option C
Explanation
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
