It is determined by the strength of intermolecular attraction; different molecules "stick" together with different forces.

In the Russian Grade 10 physics curriculum (typically following the Myakishev textbook ), focuses on measuring the surface tension coefficient ( ) of a liquid—usually water. 🧪 Quick Lab Overview: Method of Drops It is determined by the strength of intermolecular

You will need a pipette or medicine dropper, a beaker of water, a small empty beaker for collecting drops, sensitive scales (electronic or balance), and a caliper (shtangentsirkul) to measure the tube diameter. 2. Measure the Diameter Use the caliper to measure the inner diameter of the dropper tip. Convert this value to meters ( 3. Collect Data Weigh the empty beaker ( M1cap M sub 1 Carefully count exactly drops (e.g., 50 or 100 drops) into the beaker. Weigh the beaker with the water ( M2cap M sub 2 Calculate the total mass of the water: Calculate the mass of a single drop: 4. Calculate Plug your values into the formula: Collect Data Weigh the empty beaker ( M1cap

Students often need to answer control questions to complete the report: Answer Summary a beaker of water
