Question

A silver bar 0.125 meter long is subjected to a temperature change from 200°C to 100°C. What will be the length of the bar after the temperature change

Answer 1

0.124764 meter

Step-by-step explanation:

Answer 2

Using the Equation of Linear Expansion, we have:


`\Delta L =L_(o). \alpha .\Delta T \\ L-L_(o)=0,125.19.10^(-6).(200-100) \\ L=2,375.10^(-6).10^2+0,125 \\ \boxed {L=0,1252375m}`
