Quick Information

Water is the most abundant molecule in the Earth. Approximately 70% of the Earth's surface is water. It is also the only substance that naturally occurs in a solid, liquid, and gas form. The Celsius temperature scale is based on water's freezing point ( 0 degrees) and boiling point (100 degrees). Water's solid for is less dense than its liquid form. Water is also capable of absorbing a lot of heat before its temperature increases.

Why is water temperature important?

It is an important factor when assessing the water quality. It also influences the parameters and can alter the physical and chemical properties of water. Therefore, water should be accounted for when determining: dissolved oxygen and other dissolved gas concentrations, pH, and water density.

Affect from Increase in Temperature

As the temperature of water increases it will alter the density of water. This is an exothermic equation. It is exothermic because heat is being released, being that there is an increase in temperature this will shift to the reactants. because this is an exothermic reaction the addition of heat will keep it in the reactants side. If there was a decrease in temperature they would shift to the products.

Affect of Increase in Pressure

When you have an increase in pressure it will shift to the products side. I know it will shift to the products side because molecules have to collide in order to be able to form more product.

Affect of Increase in Concentration of a Reactant

When you have an increase in concentration of a reactant, this will favor the products side because you will have much more to react with.

Good Things

Water is fit for human consumption but it has to be drinking water, water that is not fit for drinking but is not harmful for humans is water used for swimming or bathing. Agriculture has the most important use of water for irrigation, which is a key component to produce enough food.

Bad Things

Deforestation, man made additions can affect water temperature. Water that is shaded by vegetation and other objects will not absorb as much heat as sunlit water. When trees or riparian canopies are removed, a body of water can become unusually warm, altering its natural cycle and habitats.
