All About Water - Water Properties and Measurements

Facts About Water

  • Water Facts: Open this fact page to learn important information about the world's water supply and the lack of clean available water.
  • Fun Water Facts: Click this link to read 33 facts about water on the website for Washoe County, Nevada.


  • Water Drops: Cohesion and Adhesion: This link explains cohesion and adhesion by using examples such as a drop of water. The page includes images along with the examples.
  • How Water Works: Open this page to learn basics about water properties. Cohesion and adhesion are reviewed near the top of the page, followed by information about surface tension, capillary action, and more.
  • The Importance of the Properties of Water to Life: On this page, readers will find a glossary of words associated with the properties of water. Adhesion and cohesion are included in the glossary.

Capillary Action

  • The Properties of Water: Clicking on this link opens up the website for Utah's Division of Water Resources page. Visitors to the website will read about capillary action as well as polarity, surface tension, and density.
  • Soil Water: Readers can learn here about soil water and capillary action. The explanation of capillary action is done in bullet-point format.
  • Capillary Action: Learn about capillary action by performing the activity on this page. In addition to the activity, the page also explains capillary action and what it does.


  • Colors and Smells: Click on this link to open a page that reviews properties of water that typically indicate a problem, such as color, smell, and taste. The page covers what water should look like and what various colors may mean.
  • Why is Water Blue?: This is an in-depth look at the color of water and why it only looks blue in large bodies of water.

Density and Weight

  • Water Density and Temperature: This page explains the relationship between the density of water and its temperature.
  • Ocean Water Density: The U.S. Navy explains here that the density of water depends on its weight divided by the space that it takes up.

Heat Capacity

  • Heat Capacity of Water: Heat capacity is one of several properties of water that this USGS article covers. Density and phases of water are among the other properties that it also explains.
  • Thermal Properties: Visitors to this page will find a layman's explanation about the heat capacity of water as well as the temperature required for water to vaporize.
  • Specific Heat Capacity: An explanation of what heat capacity is and how it works is discussed on this page. Readers will learn what the heat capacity of water is and why water is special in terms of its heat capacity.


  • Water Quality Assessment: Physical: Temperature: Click here to find out how water temperature affects water chemistry and its impact on the ecosystem.
  • Water Properties: Temperature: USGS Water Science School explores water temperature and the effect that it has on water. It also discusses how temperature is a water quality measurement.
  • Sea Surface Temperature, Salinity, and Density: Watch the video on the long-term average temperature of the sea surface. The animation also shows the average salinity and density of the sea's surface. The description explains how the earth's rotation causes the uneven heating of the water surface.



  • Water Hardness: Discover what hard water is and problems that it causes by clicking this link. The page also reviews ways to soften it.
  • Understanding Water Hardness: This page explains water hardness is and what makes it that way. Readers also learn why it is important to know what the hardness of water is.


  • pH: Get the answer to what pH stands for and what it measures. The information given is brief but thorough in its explanation.
  • Water Properties: pH: Learn the pH ranges from 0 to 14. In addition, learn how it affects organisms that are living in it.
  • Water Chemistry: Open up this in-depth look at water chemistry by clicking on the link. Learn about the physical properties of water, its pH, temperature, turbidity, suspended sediment, and more. This information is courtesy of the Idaho Museum of Natural History.


  • Condensation: Open this link to view an animation that illustrates condensation. Beneath the animation is an explanation of what condensation is.
  • Atmospheric Moisture, Condensation, and Precipitation: Review information about moisture in the atmosphere, condensation, and precipitation. The page also further reviews precipitation and both the cold and warm cloud process.


  • Evaporation: Evaporation is discussed as one of the stages of the water cycle. It is defined and the location where a majority of evaporation comes from is reviewed.
  • The Evaporation Process: On this page, readers will find two animations that illustrate the evaporation process. One animation is interactive and allows the reader to adjust wind, temperature, and humidity. The page also defines evaporation.
  • Condensation and Evaporation: Open this page to learn about both evaporation and condensation. An illustrated example of a microscopic view is on both pages.
  • Distilled Water: Distilled water is created through the evaporation process. Find out more about the process here.
  • Reverse Osmosis: Open this page to learn about the process of reverse osmosis.
