A solid metal cube of side 10 cm is heated from
10oC to 60oC. lf the linear expansivity of the metal is 1.2 x 105K-1, calculate the increase in its volume.
A
0.6cm3
B
1.2 cm3
C
1.8 cm3
D
3.6 cm3
E
6.0cm3.
Verified Correct Answer: C.
Physical Principles & Numerical Solution
Δv = 3αvΔθ = 3 x 1.2 x 10-5 x 1000
X(60 – 10) = 1.8cm
