Question

Which one of the following statement is correct for dependance of the coefficient of linear expansion of a metal rod? (A) The original length of the rod. (B) The change in temperature of the rod. (C) The specific heat of the metal. (D) The nature of the metal.

Tardigrade Admin · Accepted Answer

The coefficient of linear expansion, α depends only on the nature of material because it is the characteristic property of the metal rod. Thus, the statement given in option is correct, rest are incorrect.

Q. Which one of the following statement is correct for dependance of the coefficient of linear expansion of a metal rod?

The original length of the rod.

The change in temperature of the rod.

The specific heat of the metal.

The nature of the metal.

The coefficient of linear expansion, $α$ depends only on the nature of material because it is the characteristic property of the metal rod.
Thus, the statement given in option is correct, rest are incorrect.
