Question

do the values of coefficients of expansion differ,when the temperatures are measured on centigrade scale or on fahrenheit scale?

Answer 1

first you should know , coefficient of thermal expansion is depend only on material , not in temperature ,
but effect in difference in temperature . if we change temperature measuring scale .
in case of celcius difference of temperature doesn't change because , Kelvin scale division (100 division ) = calcius scale division (100 division).

but in case of forhenheit difference in temperature change . because
Kelvin scale division ( 100 division ) ≠ forhenheit scale division (180 division )
