Transcript of Just add water

Just add water by: Abby, Addison, Anika, and Kostia water can take three different forms. Ice, Water, and
Gas. Liquid water is a substance were all the molecules are moving at a medium speed and are close enough to stay together again far enough apart to move. A gas is a substance were the molecules move very fast and are spared far apart. Ice's molecules barely move and are very tightly packed. Water is impotent because we need it to live. Every thing in the world can not live with out water.
That is what water is. condensation:
condensation is when a gas or vapor turns to a liquid. Water is a universal solvent The ability of large bodies of water to heat water is everywhere This is a water molecule. Water is able to dissolve positive charged and negative charged molecules. This is because the hydrogen side of the molecule is slightly negatively charged and the oxygen side of the molecule is slightly positively charged. High specific heat is the amount of energy used to raise a substance's temperature to a certain amount. Starting at 100C it takes 4.2160 joules to raise 1 cm cubed of water by 1C. However it takes 1.64 joules to do the same to octane. One watt is equal to one joule per second. every living thing needs water These are all things that dissolve
in water. Salt is an example of a
solid that dissolves in water. Food
coloring is an example of a liquid
that dissolves in water. Carbon dioxide
is an example of a gas that dissolves
in water. These things are examples of
solute. A solute is a substance that dissolves
in to another substance. This forms a solution.
This all so gives an example of of a solvent. Water has great influence over temperatures in coastal cities. During the summer the ocean absorbs some of the heat leaving cool temperatures throughout the day. In the winter the water in some areas brings up warm currents. Warming the weather leaving it how it is in the summer. Some inland cities do not have weather like this. The high and low for the day will have a larger range. evaporation:
evaporation is a change of liquid into vapor at a temperature below boiling point. precipitation:
precipitation is a form of water such as rain, snow, or sleet, that condenses from the atmosphere, becomes too heavy to remain suspended, and falls to earth's surface. Water is a polar liquid.
There for it can only
dissolve polar liquids.
Water can't dissolve
nonpolar liquids like
oil. nothing would survive if water was not on earth the origin and occurrence of water
