  2. CAPILLARY TUBE WITH STAND
  3. BEAKER
  4. CLAMP STAND
  5. THERMOMETER
  6. RISING TABLE                                                                                                                         

    In this experiment, the surface tension of water is determined using the capillary rise method. When a clean glass capillary tube is placed in water, the liquid rises inside the tube due to capillary action. 

    By measuring the height of rise and the radius of the capillary tube, the surface tension of water can be calculated accurately. This experiment helps students understand the relationship between intermolecular forces, capillary action, and fluid behavior, making it an important practical application of engineering physics.

    The Complete Experimental Set-up consists of following items.
    1. Apparatus for measuring surface tension including: A fine motion adjustable stand whose height can be increased or decreased slowly. A beaker can be put over it. Three capillary tubes of different diameters & a pin fixed on an adjustable clamp and stand.
    2. Travelling Microscope : With horizontal & vertical scales. The bed is of heavy casting, thoroughly aged, machined and is fitted with levelling screws. On the dovetail guide ways slides the horizontal carriage which can be clamped at any position by means of a thumb screw. A second sliding carriage slides along a gun metal vertical pillar fitted on the horizontal carriage. The slow motion guide bars are made of sturdy material and the motion is very smooth.
      • Microscope Tube : Inclinable in any angle. True vertical and horizontal positions marked focusing. 
      • Guide Ways : The guide ways over which slides the vertical carriage is made of gun metal.
      • Scales and Verniers : Made of life time Stainless Steel.
      • OPTICS : True achromatic objective with 7.5 cm. Focusing distance from object, 10X Ramsden Eyepiece with fine cross wire is provided.
      • TRAVEL : 20 cm. horizontally and 15 cm. vertically.
      • LEAST COUNT Horizontal scale : 0.001 cm. Vertical scale : 0.001 cm.
    3. One Beaker
    4. Thermometer : 110°C
