Question
A copper wire 10 cm long is heated from 200C to 300C. Find the increase in length of the wire, if coefficient of linear expansion of copper is 1.7 X 10-5oC-1

Solution
Original length, I = 10 cm = 0 .1 m Rise in temperature, t = 30 - 20 = 10°c Coefficient of linear expansion, a = 1. 7 x 10-5°C -1
Increase in length = I x t x a
= 0 .1 x 10 x 1. 7 x 10-5
= 1.7 x 10-5m
