investigate vapor pressures and the partial pressure of gas produced from liquids at different temperatures. These pressures vary at different temperatures. In any given liquid there is a vapor that is produced above directly above the liquid‚ this can be determined intuitively from smell. (Do not smell the liquid used in this experiment‚ denatured alcohol is harmful) At a given temperature the evaporation and condensation happen at the same rate which causes an equilibrium called vapor pressure

Business Opportunity Originated‚ Screened and Confirmed Viable: Water desalination is the removal of salts and dissolved solids from saline water (brackish or seawater)‚ also known as Desalting or Desalinization. In addition to the removal of minerals‚ the process removes most biological or organic chemical compounds. Desalination systems have been used to supply potable water for coastal communities and urban centers in more than 40 countries. Desalination plants operate in almost all of the world’s

Water pollution Water pollution is the contamination of water bodies . Mostly water pollution occurs in lakes‚ rivers‚ oceans‚ aquifers and groundwater. Water pollution occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatmentto remove harmful compounds. Type of water pollutions There are many types of water pollution because water comes from many sources. Here are a few types of water pollution: 1. Nutrients Pollution Some wastewater‚ fertilizers

Deionized Water vs. Distilled Water Deionized and distilled waters are both processed forms of water. Deionized water is produced by filtering water to the point where it is free of ions. This ion-free water will strip ions from surrounding material‚ acting like a super-solvent. This is often used in semiconductor and other high-tech processing as a "soft" solvent and relatively cheap cleaning fluid. Distilled water is most often produced by vaporizing less pure source water (tap‚ salt or even

Salt Water or Fresh Water‚ Which Would You Prefer? Many people wonder‚ what big differences are between salt water and fresh water? Is it just water with salt versus water without salt? Those are some common questions people have. Most people ask about the differences‚ but they forget about the similarities of salt water and fresh water‚ as well. Did you know that Salt water and fresh water have very different plant and animal life? There are also a few complex fish that can live in both

property of water is that it is an excellent solvent. This is because of the chemical composition and physical attributes of water. Since water is polar‚ it allows water molecules to become attracted to different molecules. The attraction can be so powerful that it can disrupt the attractive forces of the different molecules. For example‚ water can be heavily attracted to salt that it can disrupt the forces that hold sodium and chloride‚ therefore dissolving it. The second property of water is its high

Paragraph on Water Water is a precondition of life. Besides various uses of water‚ it is mainly used in irrigation as India is an agricultural country. Water is a renewable resource. Life is impossible without water. Its uses are limitless whether it is in home or in fields or in industries. We get water mainly from rain‚ rivers‚ wells‚ ponds and lakes. Sea-water is almost useless for domestic or industrial purposes. India is said to be a Monsoon country. But the distribution of Monsoon rainfall

The environmental factors are conveniently grouped into biotic (genetic variation‚ stand density‚ competition‚ pests and diseases) and abiotic factors (climatic conditions

relative humidity. 3. Evaporation is a cooling process because heat is taken out of water when the process occurs. Energy is used to break the bonds that hold water molecules together‚ which is why‚ water easily evaporates. The humidity level causes the water to evaporate more quickly when the temperature is warmer. The surface temperature also has a part in evaporation. 4. The warmer the air temperature‚ the more water that will be able to evaporate into the air. It would be possible to have 0% RH

Metal-paper coil type[edit] The metal-paper coil hygrometer is very useful for giving a dial indication of humidity changes. It appears most often in very inexpensive devices‚ and its accuracy is limited‚ with variations of 10% or more. In these devices‚ water vapour is absorbed by a salt-impregnated paper strip attached to a metal coil‚ causing the coil to change shape. These changes (analogous to those in a bimetallic thermometer) cause an indication on a dial. Hair tension hygrometers[edit] These
