♥Water In Daily Life♥

Everything on this earth needs water to survive. The examples are humans, plants, animals, microorganisms and etc… Water is the common name applied to the liquid form of the hydrogen and oxygen compound H2O that bounded together by covalent bond. Water is colorless, tasteless and odorless liquid.

It is known also as the most universal solvent. Water can be classified into 3 states which are liquid, solid and also gases. Water can undergoes hydrologic cycle to change the states. The process involved are evaporation, freezing, melting, sublimation, transpiration and also condensation.

Water has the second highest specific heat capacity after ammonia as well as the high heat of vaporization which is 40.65 kJ mol⁻¹). The maximum density of water is 3.98 °C or 39.16 °F. By the way, water is also miscible with many liquids like ethanol. It can also form an azeotrope with other solvents. The covalently bonded of Hydrogen and Oxygen atoms of water can be split or break down by the electrolysis process.

The Van Der Waals Force (weak interactions) between the water molecules caused water to has a high surface tension. On the other hand, The dipolar nature contributes to water molecules' tendency to form hydrogen bond which cause water's cohesive properties. The more electropositive elements such as lithium, sodium, calcium, potassium and caesium can displace Hydrogen from water to form hydroxides.

Water is also act like a string solvent because of it universal characteristic.

Water can be considered as a nature's most important gifts to mankind. Humans need water to survive. It’s an essential source for humans to survive. Water helps humans to digest and absorb foods in our body, maintains proper muscle tone, supplies oxygen and nutrients to the cells, rids the body of wastes and serves as a natural air conditioning system. Water regulates the body temperature, also helps to alleviate constipation by moving food through the intestinal tract and thereby eliminating waste which is the best detox agent.

Our body is made up of 95% of water; blood is 82% and lungs 90% and so every people need at least 8 glasses of water per day. Drinking eight glasses of water daily can decrease the risk of colon cancer by 45%, bladder cancer by 50% and it can potentially even reduce the risk of breast cancer. Besides, drinking of water can also help to reduce body weight!

As we know that, our earth is getting polluted by mankind nowadays. And so, water is also a source being polluted by mankind. The development of technology nowadays are destroying and polluting the seas or the river on our earth. The pollution of water is measure by the pH value of the water. The pH of the water is a measure of the balance between the Hydrogen (H+) and Hydroxide (OH) ions in the water. I think most of us know that low pH is acidic and high pH is alkaline or basic. Hence a pH of 5 is slightly acidic water, a pH of 7 is neutral and a pH of 8 is alkaline water.

For the budding chemists the equation is as follows:

pH = -log10[H3O+]

The factories nowadays do not know how to handle the waste disposal and so they just simply let the chemicals flow into the seas or rivers.

I would like to say that we are just polluting the water that we are consuming everyday and it just cause harm to our self.

The water inside the photo looks clear and clean right? I took this when I travel to Redang. The water is clean enough! Hmm...Do you all wish to see this kind of water everywhere? Let's preserve and save our water from now!
