Students often need to answer control questions to complete the report: Answer Summary

. For pure water at room temperature, your result should be close to the reference value of . 💡 Typical "Check Your Knowledge" Answers Students often need to answer control questions to

Surface tension as temperature increases because molecules move faster and weaken intermolecular bonds. What if you add soap? What if you add soap

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: Measure the Diameter Use the caliper to measure

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
