A length of metal rod at 27°C is 4cm length increases to 4.02cm when the metal rod is heated to 387°C. Determine the coefficient of linear expansion of the rod........answer in step by step method please. |

Answer» Coefficient of thermal expansion = CHANGE in LENGTH / (original length X change in TEMPERATURE) So, α c /α F = Change in temp in Fahrenheit / change in temp in centigradeOr α F =α C (change in T C /change in T F ) = α C (change in T C /(9/5)change in T C ) = α C ×(5/9) = (20/3)×10 −6 |
