A horizontal tube, open at both ends, contains a column of liquid. The length of this liquid column does not change with temperature. Let `gamma` : coefficient of volume expansion of the liquid and `alpha` : coefficient of linear expansion of the material of the tube

`gamma=2alpha`

`gamma=3alpha`

`gamma=4alpha`

`gamma=alpha`

Text Solution

Verified by Experts

The correct Answer is:

The cefficient of linear expension `(alpah)` of the material of the tube and the cofficient of volume expansion `(gamma)` or the liquid, then, `gamma=2alpha`
