Alength change - 0.18 m will occur for an object that is l- 80 m long, if the coeffcient of thermal expansion is12 x 106/c and if the original temperature is 83 c, find the final temperature.

The final temperature is 270.5°C

Explanation:

Given that,

Change length = 0.18 m

Length = 80 m

Coefficient of thermal expansion

Temperature = 83°C

We need to calculate the final temperature

Using formula thermal expansion

Where, =change in length

= change in temperature

= coefficient of thermal expansion

Put the value into the formula

Hence, The final temperature is 270.5°C
