In a capillary tube experiment, a vertical $30 c m$ long capillary tube is dipped in water. The water rises up to a height of $10 c m$ due to capillary action. If water temperature increases, then the new height of water column in capillary becomes

Options:

Answer:

D

Solution:

As temperature increases, surface tension decreases ;

As $h = \frac{2 T}{Rρg}$

$∴ h$ also decreases.
