When a liquid is heated in copper vessel its coefficient of apparent expansion is 6 10⁻⁶ / ^ C . When the same liquid is heated in a steel vessel its coefficient of apparent expansion is 24 10⁻⁶ / ^ C . If coefficient of linear expansion for copper is 18 10⁻⁶ / ^ C , the coefficient of linear expansion for steel is
Options
- A20 10⁻⁶ / ^ C
- B24 10⁻⁶ / ^ C
- C36 10⁻⁶ / ^ C
- D12 10⁻⁶ / ^ C
Correct answer
D. 12 10⁻⁶ / ^ C
Step-by-step solution
We have, gathered a₁+3 ₁= a₂+3 ₂ 6 10⁻⁶+3 (18 10⁻⁶ )=24 10⁻⁶+3 ₂ ₂=12 10⁻⁶ / ^ C gathered
