The volume of a metal sphere increases by 0.30 % , when its temperature is raised by 50^ C . The coefficient of linear expansion of the metal is
Options
- A6 10^ -5 / ^ C
- B3 10^ -5 / ^ C
- C2 10^ -5 / ^ C
- D12 10^ -5 / ^ C
Correct answer
C. 2 10^ -5 / ^ C
Step-by-step solution
Coefficient of linear expansion is about one third of the coefficient of volume expansion: aligned & V V =(3 ) T & 0.003=3 (50^ C ) & =2 10⁻⁵ / ^ C aligned
