Water is one of the most widely used substances on the planet.Life as we know it wouldn't be possible without it.Water is difficult to understand at some of its basic levels.It bonds to itself in interesting ways and interacts with other chemicals in many different ways.
Step 1: Think about the chemical formula for water.
Knowing the chemical formula H2O is important.You need two hydrogen atoms and one oxygen atom to make a water molecule.If you break apart a water molecule, you will get two hydrogens and one oxygen.Splitting water can be done with electricity.Plants use water to make food.
Step 2: Think about how water interacts with each other.
The water molecule has oxygen and hydrogen in it.They share electrons.Intermolecular forces are experienced by water molecule.The hydrogen bond is the most important intermolecular force.The bonds allow the hydrogens of one molecule to interact with the oxygen of another.According to research, one water molecule is likely to form hydrogen bonds with two others.
Step 3: There is a bent structure of a water molecule.
There is a geometric shape to every chemical.Water is not an exception here.The bent structure is what each water molecule has.The shape of the two hydrogens is changed by the extra electrons in the oxygen.Lone pair electrons are unbonded electrons.
Step 4: You can read about polar solvents.
Oxygen holds electrons more effectively than hydrogen.The water molecule has a negative end and a positive end.Molecules with positive and negative poles interact well with each other.Water is a great solvent for alcohol, but a poor one for vegetable oil.
Step 5: You should brush up on acid-base chemistry.
Water can be amphoteric.Depending on the environment, it can be either an acid or a base.Basic properties of water are displayed in acidic environments.Water will act as an acid in a basic environment.
Step 6: Water can be found in three states.
Under the earth's natural conditions, water is the only compound that can be found as a solid, liquid, and gas.The water cycle allows for the circulation of water.Water can evaporate and rise, water vapor can condense and fall back to earth, and water can accumulate in the polar ice caps.
Step 7: Think about the expansion of ice.
Liquids that freeze into solid form become denser.Water is not an exception.Water expands when it's cold.Ice floats on top of liquid water.A bottle of water will often burst if left in the freezer.
Step 8: Understand the basics of fluid properties.
Water has a fixed crystal shape.We think of water in its liquid form most of the time.Liquids and gases do not have a defined shape and will fit in a vessel.The shape of a liquid and a gas is different because gases expand to fill the entire container and liquids are held closer together by intermolecular forces.
Step 9: The importance of water to life should not be underestimated.
The majority of the earth is covered in water.Half of the human body is water, and some organisms are as much as ninety percent water.There are no known organisms that can survive without water.
Step 10: Take a look at the water's polarity.
Water is considered polar since it has a positive and negative end.The water running out of a faucet can be shown by moving a magnet towards it.The water will bend in response to the magnetic field because the charged ends of the water repel it.
Step 11: Water can be evaporated from a dish.
Put water in a cup or dish.To remember how much water you start with, mark the water level.Place the water in front of a window for a while.When you come back, check the water level.Each time, mark the new level.The water is getting lower.The warm water leaves in the form of water vapor.This is called evaporation.
Step 12: Water on a surface.
Put hot water in a cup and cover it with a lid.An ice cube is placed on the lid.The hot water will evaporate as it comes in contact with the cold lid.The small water droplets will form on the lid.The best way to see the droplets is with a transparent lid.
Step 13: It is possible to expand water by freezing it.
There is a plastic bottle with water.Put the bottle in the freezer by covering it with foil.Take the bottle out and look at the results.The water froze onto the foil as it expanded out of the bottle.Don't use a cap.This could cause the bottle to burst.
