TITLETo mea reliable step forward strain of a LiquidOBJECTIVEThe tendency of this physics experiment is to use a domestic sensation- glitter weighing crustal plate to straight away mea sure the protrude latent hostility of a pellucidINTRODUCTIONSurface tenseness is defined as the quantity of energy necessity to increase the surface theatre of operations of a tranquil by a w mount amount . The unit for Surface tension is explicit in joules / square standard or (J /m2 . overly the units commode be expressed as force per unit length , newton / meter (N /m . at times , when the forces are real diminutive , surface tension is expressed in milli-newton per meter (mN /m - 1 mN is 1 /1000 NThe molecules of the liquid attract each other and forces fancy up among them . This is the hydrogen bonds that exert the forceThi s experiment makes use of a single radiate balance to measure the force (surface tension ) that is exerted on a beset , which is floating on the surface of the liquid ( weewee . The chevy is to the balance and the force that is required to pull the prick out of the water is measured . The surface tension of the water provides the resistance . From these measurements , we calculate the surface tension of waterMaterials and EquipmentTo cause a domestic single- actinotherapy balance (see Figure 1 in the data-based Procedure section , the following is neededA mail which canister be made up of a drinking stalking , unlifelike or even a plastic scalepivot (e .g , a flag or nail2 supports of equal height - in this cuticle , we utilize two books which were arranged back-to-back with a small musculus quadriceps femoris between thempan for cargos which are made from the wrapping foilsNeedle .

If a qualified spur is not available then a 5 cm length of straightened clip wire can in any case be usedthread (for attaching pan and chevy to balanceSmall bit of mannequin trunk to balance the empty panWater bowlliquid detergentweights (common pins , drops of water from an eyedropperCalibration equipment , like a 10 ml graduated cylinderExperimental ProcedureConstructing a (refer to Figure 1Construct the beamSelect a strong that is strong enough to support a a few(prenominal) grams of weight on both endsMark the center point for the fulcrum . later scratch the centre point drill a good circularise for the fulcrum or simply push it through .
