Question

2. A 65 cm length of wire is increased in temperature by 55 °C. The wire has a linear thermal
expansion coefficient of 16.5x10-6/°C. Find the change in the length of the wire. ​

Answer 1

Answer:

The dependence of thermal expansion on temperature, substance, and length is summarized in the equation ΔL = αLΔT,where ΔL is the change in length L, ΔT is the change in temperature, and α is the coefficient of linear expansion, which varies slightly with temperature.✌✌✌✌✌✌✌✌✌✌✌✌
