Question

tje coffiecient of lonear expansion of iron os 0.000011 per k .an iron rod is 10 m long at 27 degree celsius the length of the rod decreases by 1.1mm when the temperature of rod changes??​

Answer 1

here is your answer buddy!! :)

Answer 2

Answer:

answer is 17°C

Explanation:

The coefficient of thermal expansion is defined as

For linear expansion, it is just:

where

is the length and

is temperature.

is the change in length due to change in temperature at constant pressure.

For solids, we can neglect the pressure dependence, and also assume that if the temperature was increased linearly,

so change in temperature 10

then 27-10 is 17
