Consider a metal rod that is 1.42 m in length at a temperature of 14.4°C. The coefficient of linear expansion is 5.22×10-5°C-1.

Question

Consider a metal rod that is 1.42 m in length at a temperature of 14.4°C. The coefficient of linear expansion is 5.22×10-5°C-1. 
What is the change in length of the rod as temperature increases from 14.4°C to 52.0°C.

Henry · Answer

Change = 5.22*10^-5/oC*(52-14.4)oC = 1.96*10^-3 m. = 1.96 mm.
