an aluminum flagpole is 39.4 m high. by how much does its length increase as the temperature increases by 15

Sagot :

The length of the aluminum flagpole will increase by 0.00881 m as the temperature increases by 15.

The length of an aluminum flagpole may not change with temperature. While thermal expansion can cause materials to change in size when heated or cooled, aluminium, as a metal, is not significantly affected by temperature changes. As such, the length of an aluminium flagpole is unlikely to be significantly affected by changes in temperature.

Calculate the Coefficient of Linear Expansion for Aluminum

The coefficient of Linear Expansion for aluminum is about 0.000023 per degree Celsius

Calculate the change in length

Change in length = (Coefficient of Linear Expansion x Original Length x Change in Temperature)

Change in length = (0.000023 x 39.4 m x 15) = 0.00881 m
