- 2 × 2 cm piece of cotton
- One beaker containing water
- Tripod stand
- Weighing Machine.
Real Lab Procedure
- Take the cotton fabric (2 × 2 cm) and weigh it.
- Immerse the fabric in water filled in a beaker.
- Pour out the excess water by tilting the beaker.
- Place a funnel on a tripod stand and keep a beaker under the stem of the funnel.
- Take out the wet fabric from the beaker and put it in the funnel.
- Wait till water stops dripping out from the fabric.
- Now weigh the wet fabric and note your observation in the table.
- Repeat the same steps for the woollen and nylon fabrics.
- Drag the forceps towards material to collect and drop it in the weighing machine.
- Observe the dry weight of the material.
- Drag and drop the forceps towards the weighing machine to collect the material.
- Drag and drop the forceps with material towards the beaker containing water.
- Drag the beaker containing material and water and drop it at the top of the funnel to pour out excess water.
- Drag and drop the forceps towards the beaker to collect the material.
- Drag the forceps with material and drop it on the funnel to pour out any residue water.
- Drag and drop the forceps on the funnel to collect the material.
- Drag and drop the forceps with material towards the weighing machine.
- Observe the wet weight of the material.
- Observe the displayed data on the mass of material.
- Select the correct answer for question displayed related to the material.
- Click on the Next button.
- Repeat the above steps for all materials.
- After completing all the above procedures with the all given materials a tabular data is displayed comparing all the dry and wet weight of the materials and calculations.
Water absorption capacity of fibres is in the order: Cotton > Wool> Synthetic (Nylon).
