The Basics of Water

Water is one of the most important molecules in the world. It vital to the human race and all living things. Water is found in three forms: solid, liquid, and gas. 

Quick Glance: So Basic...

Water  is the most common liquid on Earth. It covers about 71.4% of the Earth. Pure water has no smell, taste, or color.

Water is one of the most important molecules in the world. It is vital to the human race and all living things. Water is found in three forms: liquid, solid, and gas. We use water in all of these states. Water is also unique in that it is dynamic and always changing. In its natural state, it is colorless and odorless.

Explore: H - 2- O

Water's chemical description is H2O. That is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom, resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side, where the oxygen atom is. Being that the hydrogen atoms are located on one side of the molecule, it binds well with other hydrogen-based molecules. It also binds well with other water molecules.

Water Facts

The tabbed presentation below will take you through the facts of water.

The States of Water

There are three main states of water. Click on each one below to learn more.

When water changes from solid to liquid to gas, the physical properties change but not the chemical properties. So, the molecules actually spread out and become more mobile. Ice is a solid and the molecules are very tight and compact. That helps to form the ice and keep shape. As it melts, the molecules become further apart and become more liquid. Lastly, as it evaporates, the gas has very loose molecules allowing it to float around.

Takeaway: What Is Your Takeaway?

My body is made up of what? Our bodies are made of water. Up to 60% to be exact. We must consume water to stay alive. The average person needs about 2.2-3 liters of water a day. 

As most of you know, our bodies are made of water. Up to 60% to be exact. We must consume water to stay alive. The average person needs about 2.2-3 liters of water a day.

Water is a vital nutrient to the life of every cell. It acts first as a building material, and it also helps to regulate our internal body temperature by sweating and respiration. Water is a big part of our waste system. It assists in flushing waste mainly through urination and helps form saliva. It acts as a shock absorber for the brain, spinal cord, and fetus and lubricates our joints.
