Extravagant Water Properties and Its Structure

    

This is a picture of water adhesion. 











    In biology, we have been studying about the different types of water properties. I have learned about the chemical structure of water and the different types of water properties. Water has a bent shape and the water molecules are polar which means that the molecules interact strongly with each other. The polarity of water is that the electrons are closer to oxygen rather then to hydrogen in a polar bond between hydrogen and oxygen. Water is polar which means it has a condition in which it has an uneven distribution of electron density. Any polar substance that can dissolve in water is hydrophilic. There are four properties of water and they are cohesion, adhesion, surface tension, and specific heat. Adhesion is an attractive force between molecules in one phase and different molecules in another phase. Trees transport water from its roots to its leaves because there are different molecules in the roots of the tree then the leaves so they have an attractive force between them. The water is held together against the force of gravity. 


   A substance that doesn't dissolve in water is hydrophobic like oil for example. Cohesion is the attractive force between similar molecules in the same phase. It can be thought of as the sum of hydrogen bonds. Water is also more dense than ice because water has more space between the water molecules. A liquid that dissolves another substance without changing its chemical composition is known as a solvent. Specific heat is the amount of heat needed to raise the temperature of a 1-gram sample of a substance by 1 degree Celsius. Copper takes less heat to raise its temperature to boil water than it does stainless steel.

Water has a high heating rate because it forms a network of hydrogen bonds. Surface tension is the energy needed to increase the surface area of a liquid by a given amount. For an example soap bubbles can remain stable in water and  its surface tension is reduced by a factor of three or more. Each molecule of water contains two hydrogen atoms and one oxygen atom. Each hydrogen atom is connected to a oxygen atom with a covalent bond. I now have a good understanding about the properties of water, and its structure.    

 Water can absorb large amounts of heat energy before it begins to get hot. I understand the different types of different types of water properties, and how they each function. There are many different water properties that makes it unique in its league. Water is the major constituent of all life forms. More than 60% of plants and animals is made up of water. I don't really understand of how to classify the type of water property, it's hard to remember the difference between cohesion and adhesion. Water is really important in life, and we build off of it all of the time.
