Question

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 1

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 centigrade

Or 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
