The Chemistry of Water

  • ice is less dense than water, which is contrary to the common idea that solids are generally denser than their respective liquids.
  • water is colourless and odorless.
  • water is a very good solvent besides substances like ethanol (an alcohol). e.g. in chromatography or dissolving ionic compounds like sodium chloride (NaCl) a.k.a. table salt.
  • there is an average of two hydrogen bonds per molecule of water.

This liquid is necessary for life!

Why is Water so important to Human Beings?

  1. It dilutes and moistens food.
  2. It assists with the regulation of body temperature (e.g. the evaporation of sweat from the skin, which leaves the skin a bit cool).
  3. It is needed for all cell functions.
  4. It is needed to transport water-soluble vitamins.
  5. It is necessary for neutralising stomach acids in the food that comes from the stomach and deposited in the duodenum (or small intestines in general).
  6. Water is used to dilute soluble salts that are in the kidneys (to prevent the formation of kidney stones) and urine.

Why is Water so important to the Environment?

  1. It is needed for plants to be ridged.
  2. it is needed for processes like photosynthesis, evapotranspiration and osmosis.
  3. It is needed for aquatic life to find shelter and a relevant and suitable environment for survival.

Earth Day 2022

  Did You Know? Earth is the third planet from the Sun, in the Solar System. Earth weighs approximately 5.97*10^24 kg. The Earth's gravity is approximately 9.81 m/s^2 (also referred to as the acceleration due to gravity). Earth's continents include: North America, South America, Europe, Africa, Asia, Oceania and Antarctica (however it is subject to debate since it is inhabitable due to its extremely low temperatures). Around 70% of the Earth's surface is water. World Earth Day Message 2022 - Environment Community Brought to you by the Environment Community

Cyclone Idai and Cyclone Leon-Eline

Looking back at two devastating Tropical Cyclones that hit parts of Southern Africa, as well as the effects of their destructions. Cyclone Eline Summary This cyclone dates back to 1 February 2000 when it was first discovered. It was also on this day when the cyclone was formed in the Australian basin. Initially it was named Cyclone Leon until it gain intensity after crossing 90 degrees east of the South-West Indian Ocean. It was at this time when it received the name Cyclone Eline (hence Cyclone Leon-Eline). A meteorological center on the French Island called Réunion, called the Météo-France office in Réunion (MFR), monitored the developments and movements of this tropical storm. Eline dissipated on the 29th of February 2000. Countries affected: Madagascar Eline reached Mahanoro on the 17th of February 2000 with winds that had speeds over 160 km/h (>99 mph).  Mozambique Landfalls were experienced at the southern part of Beira, on the 22nd of February 2000. Cyclone Idai Summary T...
