Chapter 24, Problem 1PLA

To determine

The three factors which depends on the change in length caused by temperature.

Answer to Problem 1PLA

The three factors which depends on the change in length caused by temperature are the original length, change in temperature and the linear thermal coefficient of expansion..

Explanation of Solution

Write the expression for change in length due to change in temperature

    $\Delta L=L_0\alpha \Delta T$

Here, $\Delta L$ is the change in length, $L_0$ is the original length, $\alpha$ is the linear thermal coefficient of expansion and $\Delta T$ is the change in temperature.

From the above expression, the change in length depends on original length, change in temperature and the linear thermal coefficient of expansion.

Conclusion:

Thus, the three factors which depends on the change in length caused by temperature are the original length, change in temperature and the linear thermal coefficient of expansion..
