Question

If temperature of iron rod is raised by 10°c .Then what is the rise in °F

Answer 1

Answer:

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

Here, change in length = 12mm = 1210−3m

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
