The rise of a liquid in a capillary tube depends on (a) the material (b) the length (c) the outer radius (d) the inner radius of the tube. |

Answer» (a) the material Explanation: The rise of a liquid in a capillary tube depends on (a) the material because the angle of contact depends on it. (b) the length because if the length is smaller than required the rise will be up to the tube length. (d) the inner radius of the tube because the rise is inversely proportional to the inner radius. The option (c) is not true because the outer radius does not play any role. |
