In achemistry lab, Rina took some mercury and water in two test tubes separately. Then she drained off both the liquids and on observing the emty test tubes, found some difference. Can you guess what the difference is ? Explainwith appropriatereasons. |
| Answer» Solution :Water droplets are found on the INNER surface of one test tube while the other test tube is completely dry. In the CASE of water, ADHESIVE forces are more than cohesive forces but in case of mercury cohesive forcesare more than ahesive forces. Due to stronger adhesive force, water droplets STICK to the test tube. | |
