7.The air dried filter paper was then placed on the weighing scale and results were recorded

The earliest factories in England came up by the 1730s and, with the technology enabled production processes like carding, twisting, spinning and rolling became faster and easier consequentially, between 1760 and 1787 raw cotton imports to British cotton industry rose from 2.5 million pounds to 22 million pounds. On the contrary, the traditional market of cotton cloth from India witnessed a steady decline from 30 per cent around 1800 to 15 per cent by 1815 and to 3 percent in 1870s. While exports of cloth declined rapidly, export of raw materials increased equally fast. Between 1812 and 1871, the share of raw cotton exports rose from 5 per cent to 35 per cent. This was not something triggered by the industrial revolution but the protectionist measures of the British t which imposed tariffs on cloth imports. The creation of cotton mill by Richard Arkwright brought processes under one roof and management, allowing better supervision, quality control, and the regulation of labour. Thus not only the trade the way business of production was handled also underwent a quantum change.

The lab uses the measurements of a wooden dowel in length and diameter to collect data in order to interpret data in report form. The data is used to produce statistical data and how to correctly present it. A ruler and micrometer were used to measure the dimensions. Spreadsheets are then constructed in order to generate standard deviation, mean, median, mode, frequency, as well as variation of length, diameter, volume, and cross sectional area of the

The atmosphere in a place and time in regards to heat, dryness, sunshine, wind, rain, etc.

Measure 500ml of tap water in the 500cm3 beaker, then measure 5g of sodium hydrogen carbonate using the 50cm3 beaker and weight scale and place in the beaker of water, using the glass rod to dissolve it into the mixture.

Note: General Note The Initial Measurement Section provides guidance on the criteria and amounts used to measure a particular item at the date of initial recognition.

Next, place the first set of germinating peas, dry peas and beads and beads alone in vials 1,2, and 3. Place the second set of germinating peas, dry peas and beads, and glass beads in vials 4,5, and 6. Insert the stoppers in each vial with the proper pipette. Place a washer on each of the pipettes to be used as a weight.

13) When the tray is thoroughly dry, determine its mass. Record the mass in the data table. You have to wait until day three to weigh the copper.

· I set up the apparatus as shown in the diagram. I then placed a

XII. Take the 250 ml beaker to your lab bench. Set up a gravity filtration with a plastic funnel, folded wet filter paper, and an Erlenmeyer flask. Pour the content in the 250 ml beaker slowly through the filter paper. Wash the filter paper with deionized water. Dispose of the filtrate in the proper labeled waste container.

Dispense .5 mL water into the already weighed conical vial, replace cap and face insert on its down side.

Begin by inserting a cheesecloth into a syringe and pressing the cheesecloth to the very bottom of the column.

4. Prepare a vacuum filtration apparatus using a buchner funnel. Obtain one filter paper for each one of your samples, weigh them and record their mass in your notebook (label them with a pencil to be able to differentiate them later).

Hold the test card away at an arm’s length and at eye level, while the other hand holds a yardstick just below the left eye. Put the test card on top of the meter stick. Make sure the cross on the test card is on the right hand side.
