The radius of a metal sphere is 100 cm at 0°C and 101 cm at 100°C. T

1.	The radius of a metal sphere is 100 cm at 0°C and 101 cm at 100°C. The coefficient of volumeexpansion of metal isa) 10-1°Cb) 3 x 10+8°Cc) 2 x 104°C d) 1.5 x 104°C
Answer» ANSWER: (B) EXPLANATION: In this CASE, dt=100; dl=1cm =0.01m; l=100 CM = 1m So, α = 0.01/100 = 1 X 10 −4 But γ=3X α γ=3X1X 10 −4

Answer»

ANSWER:

(B)

EXPLANATION:

In this CASE, dt=100; dl=1cm =0.01m; l=100 CM = 1m

So, α = 0.01/100 = 1 X 10

−4

But γ=3X α

γ=3X1X 10

−4
