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

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

The most common method for this lab is the , which relies on the balance of gravity and surface tension forces at the moment a drop breaks away from a tube. Objective: Determine the surface tension of water. Formula: = mass of one drop. = acceleration due to gravity ( = internal diameter of the pipette or tube. 📝 Step-by-Step Execution 1. Gather Equipment Formula: = mass of one drop

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: a beaker of water
