What is the boiling point of water?

Encyclopædia Britannica, Inc. Nearly three-fourths of Water is necessary for life. A few billion years ago the first forms of life on Earth grew in the sea. Although today many plants and animals are able to live on land, they still need water. This life-sustaining liquid makes up most of the animal blood or plant sap that nourishes living tissues. Earth’s water constantly circulates through the Earth’s water has a profound effect on where and how people live. From farming communities to the smallest villages to large cities, access to water has helped determine human settlement patterns throughout history. Livestock and crops depend upon water. One fully grown corn (maize) plant uses more than a gallon of water a day. It takes about 800,000 gallons (3,028,300 liters) of water to grow an acre of cotton. Earth’s © Lisa Lubin - www.llworldtour.com Although all water is important, it is fresh water that is needed to sustain life. Most of Earth’s water—roughly 97.3 percent—is salt water and is found mainly in the oceans. The remaining 2.7 percent of Earth’s water is fresh water—however, most of that is frozen in polar ice caps and glaciers or locked up underground as groundwater. Less than 1 percent of Earth’s fresh water is surface water, the water available for use by living things. © Ingram Publishing/Thinkstock Human tissues require about 2 1/ 2quarts of water a day. Most people drink about a quart of water each day. The water content of foods supplies the rest. An egg, fo...

Thermal properties The unit of The heat capacity of any material can be divided by the heat capacity of water to give a ratio known as the Pure water freezes at 0 °C and boils at 100 °C (212 °F) under normal pressure conditions. When At 24.70 psu When water changes its state, When water converts from a liquid to a gas, a quantity of heat energy known as the latent

The Boiling Point of Water Calculator What is the Boiling Point of Water? Water boils at 212°F at sea level, but only at sea level. Changes in atmospheric pressure will alter the temperature at which water boils. To use this calculator you will need your current pressure and elevation. How to Calculate the Boiling Point of Water Step 1: Find your local pressure and elevation Find your current barometric pressure and elevation, then enter those values in the calculator below. The following link will open in a new window. Find your location and look for the details on the page like the example to the right.

Solutions are likely to have properties similar to those of their major component—usually the solvent. However, some solution properties differ significantly from those of the solvent. Here, we will focus on liquid solutions that have a solid solute, but many of the effects we will discuss in this section are applicable to all solutions. Colligative Properties Solutes affect some properties of solutions that depend only on the concentration of the dissolved particles. These properties are called colligative properties. Four important colligative properties that we will examine here are vapor pressure depression, boiling point elevation, freezing point depression, and osmotic pressure. Molecular compounds separate into individual molecules when they are dissolved, so for every 1 mol of molecules dissolved, we get 1 mol of particles. In contrast, ionic compounds separate into their constituent ions when they dissolve, so 1 mol of an ionic compound will produce more than 1 mol of dissolved particles. For example, every mole of NaCl that dissolves yields 1 mol of Na + ions and 1 mol of Cl − ions, for a total of 2 mol of particles in solution. Thus, the effect on a solution’s properties by dissolving NaCl may be twice as large as the effect of dissolving the same amount of moles of glucose (C 6H 12O 6). Vapor Pressure Depression ...

Let’s imagine that it’s a hot day. You’ve just been out in the sun for awhile, and you’re sweating quite a bit as you sit down and grab a glass of cool ice water. You idly notice both the sweat beads on your arms and the chunks of ice floating at the top of your water glass. Thanks to your hard work studying the properties of water, you recognize both the sweat on your arms and the floating ice cubes in your glass as examples of water's amazing capacity for hydrogen bonding. Water has unique chemical characteristics in all three states—solid, liquid, and gas—thanks to the ability of its molecules to hydrogen bond with one another. Since living things, from human beings to bacteria, have a high water content, understanding the unique chemical features of water in its three states is key to biology. With most other liquids, solidification—which occurs when the temperature drops and kinetic (motion) energy of molecules is reduced—allows molecules to pack more tightly than in liquid form, giving the solid a greater density than the liquid. Water is an anomaly (that is, a weird standout) in its lower density as a solid. Because it is less dense, ice floats on the surface of liquid water, as we see for an iceberg or the ice cubes in a glass of iced tea. In lakes and ponds, a layer of ice forms on top of the liquid water, creating an insulating barrier that protects the animals and plant life in the pond below from freezing. It takes a lot of heat to increase the temperature of l...
