Question

A metal rod of length 3 m expands by 1.0 cm when heated through 200°C . Find the linier expansion coefficient of the metal. ​

Answer 1

Explanation:

Hola ji ❤

Answer ⤵️

Rise in temperature = change in length /( initial length X coefficient of linear expansion)

Here, change in length = 12mm = 12 X 10-³m

Initial length = 1 m

α=12X10-⁶

Putting all the values we get raise in temperature = 1000 degree centigrade.

So the final temperature should be 1010 degree centigrade

Hope it's help UH.....:)

Answer 2

Heya Chocolate ❤️✌️

Rise in temperature = change in length /( initial length X coefficient of linear expansion)

Here, change in length = 12mm = 12 X 10

−3

m

Initial length = 1 m

α=12X10

−6

Putting all the values we get raise in temperature = 1000 degree centigrade.

So the final temperature should be 1010 degree centigrade
