An iron vat is 14 m long at room temperature (20°c). how much longer is it when it contains boiling water at 1 atm pressure? answer in m

Explanation:

It is given that,

Length of iron bar, l = 14 m

Room temperature, T = 20° C

Pressure, P = 1 atm

The change in length due to change in temperature is called linear expansion. It is given by :

is the coefficient of linear expansion,

We know that the boiling temperature of water T' = 100° C

So, the new length of the iron rod is,

Hence, this is the required solution.
