Question

12. The radius of a metal sphere is 100 cm at 0°C and 101 cm at 100°C. The coefficient of volume
expansion of metal of metal is​

Answer 1

Answer:

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 2

Answer:

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
