Arod made up of certaon metall which had coefficiebt of volume expansion is 33×10^-6 per celsius degrer. the rod is 100 meter long and then it is heated from -10°c to 90°c. the length of rod is

100.11 m

Explanation:

Given:

Coefficient of volume expansion, /°C.

Initial length of rod,

Change in temperature, ΔT= °C

We know that,

/°C

Here, is the coefficient of linear expansion.

Now, we know that,

Change in length (Δl) is given as,

Plug in all the values and solve for .

This gives,

Therefore, the length of rod after expansion is m.
