results day 13 :)

Heyy everyone! :)

Well fortunately my experiment is almost coming to a close, im on the 13th day!! Wooo! That means only 2 more days to go! Im glad i planned the experiment to fit into this timing, because now I have 2 weeks to complete the actual report, which is exactly how much time ms zhang said we should leave to complete the report. So that is good! Anyway, here are the results for day 13!

Water evaporation:
Measuring cup 1- plain water: current height in ml: 210ml
Current height in cm: 6.3cm
Current water evaporation loss in ml: 7ml
Current water evaporation loss in cm/ mm: 2mm

Measuring cup 2- chlorinated water: current height in ml: 203 ml
Current height in cm: 6.1 cm
Current water evaporation loss in ml: 10ml
Current water evaporation loss in cm/mm:3mm

Measuring cup 3- chlorinated water with liquid pool cover: current height in ml: 220mm
Current height in cm: 6.6 cm
Current water evaporation loss in ml: 13 ml
Current water evaporation loss in cm/mm: 4mm

Measuring cup 4- chlorinated water with solid pool cover: current height in ml: 214 mm
Current height in cm: 6.4 cm
Current water evaporation loss in ml: 3 ml
Current water evaporation loss in cm/mm: 1 mm

Colour and appearance:
Measuring cup1- plain water: this is pretty much the same as day 11 in terms of colour and clearness of the water. Once again the small, tiny bubbles are moving more towards the bottom of the cup. This is a big change from day 1, when all the bubbles were evenly dispersed amongst the cup.

Measuring cup 2- chlorinated water: this also is the same as day 11. The colour and appearance of the water in the cup is still clean and clear with no bubbles, this is expected.

Measuring cup 3- chlorinated water with liquid pool cover: there once again is not much change. The liquid pool cover still looks like bundles of murky clouds at the surface of the chlorinated water, and also, at the very top surface of the chlorinated water, I have observed little dots starting to appear.

Measuring cup 4- chlorinated water with solid pool cover: the same as measuring cup 2 for colour and appearance.

Ph, chlorine, alkalinity and stabiliser content:
For all the measuring cups, this is the same as both days 1,3,5,7,9,11 which were all the same. Although the different waters are being evaporated from the measuring cups, the Ph, chlorine, alkalinity and stabiliser content will remain the same in ratio to the amount of water remaining.
